I just saw this episode this afternoon (the WB station pre-empted it last week for some basketball game). I'm not a big Superman fan, although I am somewhat familiar with his origins and history.
I should state up front that this was the first episode of "Smallville" I've ever seen, and even then it was at my wife's urging (she's seen it once or twice before, but she especially wanted to see Christopher Reeve). I thought it was pretty well done, and I appreciate the fact that so far in this thread everyone's had nothing but raves for the episode, so I sort of hesitate to mention this, but there was one thing I really didn't "get."
Clark's vision starts to go wonky, and then all of a sudden he's doing a Scott Summers/Cyclops routine - okay, that's Superman's "heat vision" kicking in, I get that. But what I don't understand - and maybe you long-time viewers can help me out here - is how did his heat vision manage to carve a Kryptonian symbol into the side of the barn? From my understanding of Superman's heat vision, he would have had to have specifically focused his heat vision on each point of that symbol to burn it into the wood. And it certainly didn't look like he was doing that.
Okay, from a "plot" sense I can see that was necessary - because the writers needed Chloe (is that her name? the reporter girl) to shoot a picture of a Kryptonian symbol and get it published in a newspaper so the Christopher Reeve character could see it and get in contact with Clark. But realistically, it didn't make a whole lot of sense to me.
Anyone care to enlighten me? I'm not trying to pick apart the show - all in all, it was very well done. And heck, since it's the only episode I've ever seen, I guess I can even join the "best episode ever" chorus.
