Year One

Impressions before seeing it
I heard it was basically a bomb, but I like the cast and crew so I thought I'd give it the benefit of the doubt.

How was it?
I don't think Year One is terrible, I just think it's forgettable. Jack Black and Michael Cera had previously established themselves as capable comedic actors, but this movie just ended up being a star vehicle for their on-screen personae. We know too well that Black almost always plays the lazy, bumbling idiot and Cera almost always plays the awkward, cowardly loser, so basically Year One attempts to write itself by basing a lot of the humour on these typecasts, placing the characters in an era where having these qualities made it very hard to fit in and be successful. I did find some of it to be funny, because I personally don't mind seeing Black and Cera play the same characters all the time - they're good at it - but it may have been overkill to make them both leads in the same movie. Too much unoriginality at once. A shame, because it should have been better given that it was written by Harold Ramis and two former writers from The Office.

Recommendation
If you really like Black and Cera, then I suppose it might be worth watching once for a few laughs, but it's really not a movie that needs to be watched twice. The jokes are not hilariously everlasting and the story/adventure is not entirely exciting, so once again the most appropriate word for this movie is "forgettable."
