For anyone who may not know what a one-actor movie was like, this is the best example. This plot is ridiculous, and really makes no sense. It's full of cliched situations, hackneyed lines, melodrama, comedy... you name it!But Amitabh Bachchan can make anything convincing, and this movie is by no means an exception. Everyone turns in a decent performance - Shashi Kapoor, Waheeda Rehman, Ranjit, Om Prakash, Smita Patil... But it is the Megastar who overshadows everyone with his towering presence. Without him, this movie would have been a non-starter... The story is about separation / mistaken identities / misunderstandings / love / hate / loyalty / good vs evil - everything, really! Amitabh's is a brilliant performance on all counts, in an otherwise silly film! And did I mention that it is ridiculously funny?
