We discovered this by accident, and absolutely loved session one. Laughed our assess off!
Andy Samberg is absolutely great in playing the goofy annoying but loveable step-son, driving the always genius Greg Davies up the wall.
We started season 2, but not loving the acting of the new guy. Maybe it's a European thing, but the acting of the English actors seems way better than the new American guy. Apparently he has done big roles before, but contest doesn't seem to be his knack. (Andy's screwball comedy was awesome contrast with the English humour though!)
The new actress playing Rachel is a bit boring and in no way as good and funny like the actress from the first season.
Don't think we'll make it far in season 2...
