I have to say this was a lot less funny that it should have been, probably about five genuinely funny laugh out loud moments, but far too many gags that just weren't funny.
Brand was actually puite good I thought, though not really having to stretch himself, he was quite obviously allowed to ad-lib a lot and it worked very well I thought, Jonah Hill was brilliant as ever, can't wait to see those two together.
THe film was helped, for me, by the presence of Kristen Bell and Mila Kunis both not wearing much a lot of the time **droooooooooolllls**
I still find myself agreeing with Mark Kermode though, the Judd Apatow model of slobby bloke getting together with ludicrously georgeous girl (or two in this case) is getting a little tired for me.
