Confession: I saw the French original (L'emmerdeur) in French (I am a French translator) and was totally entertained. When I saw Bumboo, however, I had no clue that it was a remake (after purchasing rights). I was totally entertained again. The best part is that this film has been very well adapted and in fact is in some ways better than the original. BTW, I felt the same about Bheja Fry, which again is a copy from a French film by the same writer.
Small budget films are harshly massacred by high-brow critics. I see it happening with Bumboo too. Most reviews always fail in India because they do not give importance to the entertainment quotient. This is an entertaining film with full value for your money.
The plus points of the film are: excellent adaptation of the original plot; sticks to the original quite closely; local humor; not too much of crass or vulgar comedy. The taste of most of our audiences have been ruined by crass comedies -- so the audience may find this refined comedy difficult to understand and digest. Of course, some bits of hamming, crass jokes are there.
The negative points: the original script was good, but in the adaptation the same level of perfection is not there. Some average jokes (mainly because of the low budget) have crept in. Due to low budget perhaps stalwarts like Vinay Pathak and Rajat Kapoor are not there. They would have taken this film to an entirely different level. Most of the cast are just about adequate. Sterling performances would have really raised the bar of this film.
Excellence in script writing is what this film lacks. Which is sad because no real effort on the story was required. Direction too is just about good. With better scripting and direction, this film would have been a hit. Better acting and the film would have been a super hit.
Do watch the film because it is highly entertaining -- despite its several faults.
Want to end with another confession: I was so engrossed in the movie and laughing out aloud that I had no time to check the reactions of the audience.
