Nani (Nani) is in love with Bindhu (Samantha) which she does not reciprocate though she has a soft spot for him. When Sudeep (Sudeep) who is a millionaire and always gets what he wants has his eyes on Bindhu, realizes that she is in love with Nani. Sudeep kills Nani to clear his way to make advance on Bindhu. Nani is reborn as a housefly and vows to avenge his death and protect his love.
Let us first try to dissect the ridiculousness of the plot. The fly (Eega in Telugu) does not have any telepathic, telekinetic or healing powers. It is just a common housefly but with a determination. How can it possibly affect a bull of a cruel intelligent man with everything at his disposal defines the innovative script. Rajamouli throws in a healthy bunch of ideas on what all ways that a housefly can give literally sleepless nights to the antagonist well helped by accepted norm of coincidences in Indian cinema. Adding to that the lead female character is a micro artist who extends her expertise to equip the housefly with a mask and weoponized gloves.
When it comes to a default Rajamouli movie there is a certain pattern that he normally follows. The protagonist is a regular guy who gets placed in an extraordinary circumstance while inducing all the commercial elements of song and action sequences in the precise positions delivering a guaranteed hit with the masses. Here he sheds off everything that made his earlier blockbusters (well most of it) and comes up with a fresh presentation that works wonders. A special commendation to Sudeep, though he plays your default villain of Telugu cinema - does it with comic book style panache. Background score by M.M. Keeravani is as usual elevated for Rajamouli movies, cinematography is excellent especially in the stages when the fly is just born. Samantha has an important but a very simple role to play and she does a decent job. The extended climax is completely unnecessary and it is intended especially for Telugu audience craving for a happy ending. Another important aspect to be considered here is that, when taken into account of other creature based movies like 'Finding Nemo' or 'A bugs life' or even 'Wall-E', all these characters have a well defined face (at least eyes and eye brows) which help the animators show real expressions which was not possible here. The animators have to rely on just body language to show all the emotions where they do an excellent job.
Original, creative, audacious and ridiculous.
