Television wise I would pick:
Firefly
Buffy
Angel
Two and a Half Men (Charlie Sheen years)
The New Adventures of Old Christine.

Season grade: A+++++

"With the generators blown, the army outside the main door–which the
Mountain Men leave unguarded because they believe it to be impenetrable
(see, that’s what a contrived narrative moment looks like)–is free to
explode the seal and start the actual rescue."

The thing I always wondered was why did they do that in the first place? What's wrong with showing the title Whore? It's not like the title for the True Blood episode Fuck The Pain Away? That makes sense (in more ways than one going by this past season) for censorship.

I was really looking forward to seeing if Lesley could pull off the action scenes, so that was the biggest letdown for me.

Same here. I remember watching an interview where DeKnight mentioned that by this episode they felt they had worked out the kinks. Gone was the cartoonish CGI blood , to be replaced by much more efficient SFX.

Of what I've seen:
1. The Lego Movie (B+)
2. Captain America: Winter Soldier (A+)
3. X-Men: Days of Future Past (A-)
4. Godzilla (B)

Agreed, I was just talking to my sister yesterday and realized this is the same season with Deucalion, The Darach, Cora, etc. The long break between seasons made me forget.
But this is the best season to date.
