The series IMHO was really good. But the first film was a complete let down.
I think the mistake was taking them out of their environment; it works with somes shows,but not all.
I hope this film is better, but I'm not holding my breath, judging by the last one.
As I said, I like the series, but I do think people feel compelled to like the film/s because it' currently fashionable.
There have been lots of comedies over the years that have been incredibly popular, but are crap.
The one that springs to mind for me was "Friends".
