Making a suspense thriller is tough. To keep the audience attentive, besides keeping the viewer guessing till the end, requires complete understanding of the craft. Deepak Tijori had attempted a suspense thriller earlier [most storytellers have a penchant for this genre] and Fox, a complex theme, is more of a challenge for him. So, does Tijori get it right? Initially, yes. But Tijori loses it all towards the post-interval portions. The culmination is the thorn in the flesh.
Strangely, most film-makers in Bollywood just don't give a proper conclusion to suspense thrillers. The wrap up is just not compelling, with most films running out of steam in the final leg. Fox falls in this category. Verdict? This fox lacks the bite!
Arjun [Arjun Rampal] is a successful criminal lawyer whose knowledge and aggressive interpretation of the law makes him a name to reckon with. He is reputed to have never lost a case and can get anyone acquitted, no matter what the crime. No wonder then, criminals swear by his name.
