A lot of people are offended that they copied the "original" version and they are citing Michael Scott's character. The actual original was the British version by Ricky Gervais and American writers faced the exact same hate when they were writing season 1 of the US version. It all turned out well in the end.
Writing in this Indian version remains faithful to the American one with some minor changes. The acting is GOOD, especially Gopal Datt! I don't know why anyone would say it's horrible.
Is it as good? No.
Is it as bad as the rating makes it look? No!
Overall it deserves a better rating than the 3.5 it has now. Give it a chance. If you haven't watched the American one, you will likely get some chuckles out of it. If you have, It will at least not make you cringe. It's decent enough.
