Perhaps it's because I never could buy into the fact that any sane human being would be macking on someone else right after they colour-yawned, but I never for a second thought that House and Cuddy would have hooked up as House detoxes. Cuddy tries her best to be as appropriate as possible when it comes to House. No one might ever find out about their one night stand, but it doesn't mean that it won't eat away at her for having 'taken advantage of her mentally incapacitated employee'. This woman is motivated by two things people, guilt and propriety.
I don't see what's there to bitch and moan about. Fangirls got what they wanted: the long-awaited
While I am not the hugest fan of the hallucination, it actually allows for a much better view into House's mind. IT DEVELOPS THE CHARACTER. I am assuming that it's a good thing, seeing how we (or at least I do) prefer characters who are not just 2D cutouts. By having House and Cuddy interact with each other in the 'aftermath', it doesn't negate all that has 'happened'. Instead, I think it just goes to show that House came to the same conclusion we've always rooted for: Lisa Cuddy is THE ONE. Shouldn't we be happier about that? Sure, it's bittersweet but it's there. For frak's sake, he just about asked her to move with him!
The hallucination is less of a copout on the relationship level than it is on the story writing front. As Sepinwall said, more hallucinations? While his Shyamalan comparison can be regarded as an unkind remark on the writing team's ability to bring their A game, (I personally think there are worse names to be called. I loved The Village) it's more to do with how the audience was never given a chance to solve the mystery themselves. I personally believe that good storytelling shouldn't be about throwing new elements at your audience. Good storytelling should expand upon elements that are already there. For example, Chuck did a fantastic job with the Tron poster and slow build up over two seasons. They didn't decide to deliberately confuse the crap out of you just for the heck of it.
Also? We aren't left hanging with a giant question mark as to whether House the show will come back. We're gonna see further interactions between House and Cuddy. There's gonna be more because this is a paradigm shift, whether you like it or not. Unlike that other show I love with my entire being and hasn't been renewed...
Paradigm shift + things left unsaid + possibilities + confirmed season six = MOAR.
Paradigm shift + ill-timed interruptions + an almost confession - confirmed renewal = bitterness. /disgruntled rant from a Chuck fan.
