That's actually good, if you think about it, because the entire premise of the show originally was about Clark's high school life in Smallville; it wasn't originally intended to last so long that he'd be done with college and working as a reporter for the Metropolis Daily Planet and dating Lois Lane etc.
What would be even better would be if the same people then did a series revolving around the Justice League. Hell, with Green Arrow a regular in Smallville and Chloe serving as "Watchtower" they're already partway there as it is.
While looking for pictures of Allison Mack the other day I came across a news bit/rumor to the effect that she's only in five episodes of this season. *weep, wail, gnash teeth* But since it's the last season I'll watch it to the end instead of abandoning it after her last show. WTF, I've seen it from the beginning; with the end in sight, I might as well finish it.
The guy who played Lex Luthor in this ep--he was so not Lex Luthor. It takes more than a shaven pate to make a guy into Lex Luthor, and that guy was just not it. WTF, won't Michael Rosenbaum come back for the last season? (The guy appears to do a lot of voice acting for cartoons, according to his IMDB entry, so why not Smallville?)
(OTOH, SPOILER he was supposed to be an inferior clone of Lex, so that sort-of mitigates it. Still /SPOILER)
The ep felt a bit rushed. The solution to the cliffhanger end of last season was exactly what I had expected it to be. All told, though, I liked what I saw.
