I don't have anything personal against Will Ferrel. For me, when he's funny he's funny. When he's not, it's not even close.
This movie, ironically, didn't find me at all irritated or not laughing at Ferrel. What really pissed me off was that it was just stupid. There was so much potential (in my mind I guess) that what I saw was a big disappointment. Marky-Mark's character just flat out made no sense some times. He would snap for no reason. At least justify some of that stuff and I'd be happy.
But the biggest issue I had was the premature-exit of Dwayne and Sam. I didn't mind their roles were glorified cameos. But come on. The way they were "dropped" from the film was just flat out stupid. At least make it make sense. I'd of even settled for them being on the take, and Wahlberg and Ferrel had to bring them down. That would have at least made sense considered Ferrel's character's approach to policing (i.e. paperwork is his friend).
It's a bummer for me. The funny moments were definitely there (accidental pimp, hot wife confusion, deer vagina). But the rest of the film was just sorta there and frustrating. Oh well.
