Guddu Rangeela is a 'hatke' film with the Khap panchayat and its misogynist "honour killing" mindset as the backdrop. It is not entirely a serious film as it also has some well-placed comedy in it.
MERITS of Guddu Rangeela
1 - Fine acting by Arshad Warsi & Ronit Roy esp. with the Haryanvi accent
2 - Pulsating & thrilling background music
3 - Interesting twists and surprises in the tale
4 - No cheap melodrama in acting or dialogues
5 - Very good pacing and build-up of the film
6 - Funny dialogues and funny characters are presented very well and these "merge" very well with the story (without looking "forced")
7 - Great speech by wife of Arshad Warsi on the hypocritical and misogynist mindset of the barbaric Khap Panchayat
DeMERITS of Guddu Rangeela
1 - The ending is horribly melodramatic involving bloody fights and shoot-outs between the bad guy and the good guy! The kind of scene you will get to see in a 70s or 80s film. (It seems Subhash Kapoor ran out of ideas and decided to end the movie in this totally cheap way)
2 - Amit Sadh & Aditi Rao Hydari got married, but this was not shown properly at all. It was shown, after the film ended, in a totally flimsy and casual manner in a series of visuals which also included film-shooting scenes.
What rubbish is this!
3 - Aditi Rao Hydari's sister committed suicide unable to tolerate a brutal husband (Ronit Roy). And then we see Aditi visiting Ronit's house and living there, with the clever idea to secretly record his bedroom activities with a prostitute.
What looks totally unrealistic is that Ronit welcomes her (the sister of his wife with whom he never had any previous relationship) to the house by warmly embracing her!
