A little late on this bandwagon, but who cares.
I usually end up throwing money away when I buy something impulsively, but I saw this set leering at me and couldn't help it, so I dropped the $50 having never seen the show, but going off of some of your recommendations (Virex never leads anyone too far astray...).
Damn, it's such a good, character driven, well-written show. No wonder it got creamed in the ratings. This show is a perfect example of why some programs need a little time. The kids really developed into their characters; the only good actors in the first episode were James Franco, Linda Cardellini, and Samm Levine, but by about the seventh episode, all of the actors had come into their own and the show was really rolling along.
Linda/Lindsey is such a babe, too. She's freaking Velma from the Scooby Doo movies. What a fall from grace....
James Franco gives me all kinds of man love goosebumps. What a babe.
And all the Star Wars stuff....just awesome. On that note, I noticed something a little...well...convenient. Lots of the episodes were either written or directed, or both, by Jake Kasdan, who is Lawrence Kasdan's kid. Lawrence, as we all know, was the writer for The Empire Strikes Back, so there's obviously an in.
Another thing I noticed was that another frequent contributor to the writing and/or directing was Rebecca Kirshner (she's also apparently done a lot of work on Wheadon's Buffy series). And Irvin Kirshner, of course, directed TESB. That's not a terribly common last name. IMDB doesn't say anything about a relationship, but I'm willing to bet there's something there.
Anyway, it's a great show. Eighteen episodes for fifty bucks is a great deal, and well worth it. Haven't watched any with the commentaries yet, but I'm looking forward to it.
