The Good:

*Chemistry of the three leads
*Humor (mostly)
*Action, surprisingly visceral for a buddy cop flick
*Score
*The inner conflict of the main characters

The Bad:

*Plot got too convoluted towards the end (granted, this always happens in this type of movie so I guess it isn't that great of a flaw)
*The lack of a clear villain
*Occasional jumpy editing

Overall:

So fun that for the most part you won't notice the flaws
