SPYder wants to be a clever cyber spy thriller but is more a vigilante story with some bells and whistles. Mahesh is a compelling presence, and Rakul Preet Singh is a good match for him. But AR Murugadoss seems to have lost his own plot in the second half

Warning: Some mild-ish spoilers follow.

Shiva (Mahesh) is wildly overqualified to be an intelligence officer, tapping phones illegally albeit with a government mandate to break that law in order to proactively stop people who may break other laws. Hmmm. He is also a genius software developer. One of his inventions analyses calls for signs of fear and pleas for help. When Shiva gets the bat signal he may go rescue people himself, or call on supporters who know of his sideline. On one call he “meets” Charlie (Rakul Preet Singh), a medical student interested in finding a friend with benefits. Through another call he unwittingly sends a friend to her death. Sickened by the consequences of his outsourcing, he finds proof the murderer is a serial killer. Shiva sets out to find him and obtain closure for himself and for all the victims. What starts out driven by data and psychological profiling soon turns into a series of tactical encounters.

Shiva is judge, jury, and executioner as he knew once people went into the legal system it was pointless. Mahesh plays Shiva as focussed, and kind of grim. And Shiva does so much talking – dialogues, voiceover, exposition… Despite the high stakes cat and mouse game, there are times a lighter touch would have been welcome. The scene where he chased Charlie’s auto, jumped in and asked her two questions, then jumped out and ran away had a nice flavour of deadpan absurdity. But when he ran towards the evil Bairavudu, the fierce emotion and torment he was feeling was palpable. Mahesh is a seriously good actor and I was a little disappointed the material let him down.

For those tracking Mahesh’s reluctant acquiescence to the shameless skinshow, he did wear tshirts, and flashed a glimpse of ankle in some manpris. I feel that the costume designer has been watching a bit of Kpop lately, with asymmetrical tailoring supersized to fit Mahesh’s lanky frame. I am grateful he went the mesh shirt (over a tee) and let the dancers don the mesh pants. He hasn’t varied his dance style from rhythmic hopping and emphatic pointing.

Mahesh, maaaate, it’s not the 90s anymore. The songs make a visual statement but musically they do little to lift the movie. And the English lyrics in Achcham Telugandham are woeful…hopefully deliberately!

A scrap of cloth at the scene of the double murder had traces of blood from 8 more people. And then a character said “and three of them were men”. Yeah it’s not like 7 women had also been killed. Someone think of the men! Also the stalking trope is given a twist but it is still stalking. Charlie confronts Shiva early on but as his mate Varun (under-utilised but highly likeable Priyadarshi) says, she noticed what he was wearing so of course she must have fallen for him. The “but she secretly wants it” explanation left a bad taste as did her cheerful acceptance that it wasn’t a big deal if it was Shiva tapping her phone.

Despite all the macho BS, the ladies fare quite well. Charlie wants sex without silly romantic shenanigans and decides Shiva is just right. She says to his mum “I’m 21. My parents have been married 20 years. I take after my mother!” and wins maternal endorsement to try her luck. Rakul Preet Singh has pep without being a manic pixie. Charlie was assertive and still a bit girly, and it was a pity after the boulder incident when it seems everyone forgot she was in the movie and ran off to the next scene without her. Charlie just gets to stand around in the background a lot despite all the likely issues with professional ethics, police procedure, and common sense. It was a waste of a competent actress.

In one of the best sequences of the film, a bunch of neighbourhood mums and aunties are persuaded to help Shiva in a dangerous rescue. He is in a van driving through traffic as he gives each of them a task, and they get shit done in magnificent style and to great music. The aunties not only saved the day but probably booked in coffee catch-ups and shopping trips as they climbed up poles and leapt across balconies. The audience, including me, cheered.

There’s some glossing over and leaps of faith required to buy in. Technology that can record, analyse, prioritise calls in real time from all across Hyderabad whether on analogue or digital networks and presumably in any language sounds great. But I can’t even get a Google doc to load on my work laptop! Shiva just happened to have a green screen handy when he needed to interrupt an evening soap. And he always knew exactly which of all the variables to choose, just on his gut instinct.

Bhairavudu (SJ Surya) is a nihilist and a sadist. He has no objective other than killing for the sake of it, and feel entitles to inflict pain. He is a creature of death and hatred, born in a graveyard. Surya is effectively menacing when he is passing through crowds or observing his intended victims, a cold hunger emanating from him. But when he starts with the capering and shrieking, it’s just acting crazy and it doesn’t ring true. What was with the hessian gimp mask? He could have done with more restraint, and Mahesh could have boiled over a little more and I think the second half would have been more compelling.

Jayaprakash is Shiva’s sensible dad and I think Dheepa Ramanujam plays Shiva’s sensible mum. RJ Balaji and Priyadarshi Pulikonda play Shiva’s down to earth work mates, both low key with the occasional laugh arising from their reactions to their heroic friend. I think the villains were instructed to overact because Bharath tries to get his teethmarks into the scenery.

You’d expect anything Santosh Sivan does to look amazing, and SPYder is very stylish. There are some good, and some dodgy, CGI effects, and the action sequences are full throttle. AR Murugadoss had a good idea but didn’t work through the detail to ensure the finale was as satisfying as the start of this larger than life conflict. Nevertheless there is plenty to enjoy, especially for the Mahesh fans.
