Buffy - The Body
The most mind-blowing, devastating episode of TV I know.
Angel - Not Fade Away
My favourite finale by far. Exciting, tear-jerking, epic.
Seinfeld - The Junior Mint
The funniest TV episode I've ever seen. I used to prefer The Contest, but this stands up to repeat viewing better. Jerry's plot: he's dating a woman but can't remember her name. This is the funniest sitcom plot bar none.
Six Feet Under - Everyone's Waiting
Strong episode overall, but those last six minutes. If you've seen that montage, set to Sia's Breathe Me, you'll know what I mean.
Battlestar Galactica - Daybreak
I know a lot of people hated the BSG finale, but I loved it. The last scenes between The Old Man and Madame President can make me well up just thinking about them. Plus: All Along The Watchtower.
Veronica Mars - Pilot
Best pilot episode I've ever seen. Loaded with so much exposition you'd think it would be impossible to make work, but it's moving, funny and charming.
The Wire - Mission Accomplished
Picking just one Wire episode is borderline impossible. It's like picking a favourite page from a novel.
Mad Men - Far Away Places
Roger Sterling is on acid. Perfect.
Firefly - Serenity
The brilliant pilot that hinted at a darker, more adult show than Fox could evidently live with. Unfortunately the vastly inferior Train Job ended up subbing as the pilot when it went to air.
Arrested Development - Let 'em Eat Cake
"He's thinking about bees again."
