If you were looking forward to this film, you're going to be disappointed.
It's a lot like one of those awful sequels where they're desperate to inject humour because the first film(s) were clever, but also happened to be funny - one of those "we had a lot of fun making the movie", movies. Yeah, probably more than we had watching it.
Maybe it's cos nothing really happens ...maybe I'm just bored of the genre. I didn't enjoy it, and probably won't bother with the others.
