Oh yeah, and besides sarcasm, House is completey different from Cox. Cox rants and speaks in monologues, while House is sharp, focused, and releases his wit in bursts. Thinking they are the same is another example of many people's tendency to oversimplify.
Honestly, if House is formulaic, every other show is as well. The whole point is that they diagnose diseases that are hard to diagnose. The red herrings are necessary. What makes it different, like most Law and Orders are different from each other, is the type of illness, the effect it has on the characters, and whatever shit Laurie does.
