"The Other Guys". One of the 38 or so Ferrell/Wahlberg collaborations.
The wife picked this one. She likes Wahlberg. Ferrell, personally, is about as funny as an enema and I usually avoid his "skit" movies.
I did like this one, however, mainly because Ferrell had no hand in writing it. That means lesser characters can flesh out and sight gags are there, as well, if you pay attention. Samuel Jackson and The Rock are funny as hell in the first few minutes and Michael Keaton, Steve Coogan and Eva Mendes steal the rest of he show.
I even laughed at Ferrell twice. Or, maybe, once.
3/5 for trying.
