I'm not a huge fan of bollywood films but have seen a few. This may not be one of the finest around but it is very entertaining. Great story with some fantastical whims thrown in there. The lead actor is one of bollywoods greats. Some nice scenery shots and as mentioned some funny 'far-out' scenes which would be essential in any 80's film. They've really packed everything into this film. If you don't want to sit through the 3 hours or so then at least watch the first and last 30minutes or so but you really should sit through it.
Give it a chance. It's just over a 3.5 from me so hence a 4 star and i would recommend it to people who like abit of action, comedy, the bizarre, musical oh and old kung fu films as the film quality is probably the same - though the amount of effort in production in this film is far better.
