With two major names in the Malayalam literary world - Benyamin and Indugopan - sharing screenplay credits, I wouldn't call it wrong to expect greater depths to the protagonists, a well-etched romance, and some situational humour. But Christy is flat from start to finish; its positives include a soulful score by Govind Vasantha (who infuses a 96 hangover to several scenes) and aesthetically pleasing shots by Anend C Chandran.
Mathew Thomas is okay in the initial portions where he has to play a confused teenager in love with an older woman, but the writing leaves him absymally ruined in the second half. Malavika Mohanan is extremely photogenic, but her dialogue-delivery needs to improve. The dubbing is also bad, and her Malayalam comes off as a bizarre blend of Payyannur slang and an NRI accent, with forced Trivandrum phrases added in. As the titular character, we barely get to know what's going through Christy's mind in various phases of the film. This includes her failed marriage, her thoughts on Roy's abrupt proposal, how she feels about being held by the waist and kissed reluctantly, what she thinks about having to move away from home, and so much more.
Everything that could build to a solid character arc is brushed aside to portray a version of Christy that smiles 99% of the time, courtesy of romanticized clichés such as sudden rains, beach waves, bus rides, and everything customary. Roy's immaturity in love is somehow passed off as something unconditional and great, especially in that tame final act playing out at two different airports. Since the complexity presented here is technical rather than emotionally-affecting, these scenes fail to leave any sort of impression. The bigger blame, no doubt, should be directed towards the bland writing. Also, a Trivandrum-based film strictly needs more Trivandrum-based actors.
