The whole bomb sequence was great. Dying especially at "Okay, sounds like we were successful. Is there anything else I can help you with today?"
It was a finale, alright, but somewhat underwhelming on all fronts. The fact that Shane really was the killer like they aluded to at the very begining isn't even the main problem. Is Rachel's "realization" supposed to be due to "tough love" or what? Nicole only needed a "manly man" to come save her from a life of independence and fix their marriage in one fell swoop. And of course Paula is the only guest that suffers some form of consequence for her actions, and I mean the fact that she's really stuck with Olivia now.
It all makes up good satire but it's all too real and fatalistic, which I didn't expect from the build-up.
