I watched a few episodes years ago, and I thought it was absolutely rubbish. Then when it came onto Foxtel just recently I actually watched the first two or three from the start and got a better feel for it, now I love it.
It's pretty good. Definitely the best sitcom atm, but that's probably mostly because the rest (Big Bang Theory and Two and a Half Men) are like a string of shit dangling from your ass. Doesn't really compare to Seinfeld and the like though IMO.
Like Scrubs I didn't use to really like it but again like Scrubs I got used to it and now love this show.
I think you mean American...unless you watch those hilarious Indian sitcoms...and meant English-speaking
Indian comedy sitcoms barring the odd one are not very good. Meant English speaking in the sense that there could be comedy Sitcoms better in other languages like Spanish,Italian etc.. for all you know.
I reckon you should give it a chance. The first couple of episodes are a bit meh, but after that it turns into the best show I've seen in ages. If it keeps it up for a third season it could rival AD, AFAIC. Wouldn't say it's anything like Modern Family tbh, which I'm not really a fan of.
The amount of effort they go in for Barney is awesome. Von Materhorn actually has his own websites if you check and he has his own blog online
