Looks like they're doing a re-revamp of Superman and this time using a new actor. Frankly I liked the Brandon Routh as Clark Kent/Superman, he did a good job I think even though the scrip could have been reworked a bit. Sorry but the kid in the film could have been Sup's kid, but if you remember in Superman II (and no I don't consiter the Richard Donner version canon. I consiter the one I first saw canon) Clark had "snu-snu" with Lois AFTER he lost his powers. There for the kid would have been a regular person. So how did ther piano kill the bad guy you say? Either the boat hit a wave causing the piano to come lose and whammo or the kid had a boost of adrinaline and shoved the piano while the boat hit a wave who knows it was off camera when it happend. But what about his reaction to the Kryptonite? The kid could have just been really scared of Lex Luther and had no idea what he was going to do to him. Heck have a mad man wave something in front of yea, you'll be scard too.
Anyway they're using a new actor who really doesn't look like he'd make a good Superman so I might skip this next film.
