Exactly! I do like buddy films, right up until the point where the guy gets the girl and the buddy becomes a third wheel. T_T The last two or three minutes of KKBB was me going "WHAT. WHAT. WHAT. YES. WHAT. YES. =D"

Though, I once watched a chinese buddy movie where I felt it was done right, although the buddy is dead for most of it and there was like time travel and shit... but the main character's mission was to bring him back, and when the female sidekick threw a hissy fit at some point, he basically told her "I like you, but fuck you miss, this is about my friend, not you."
