The censors in the UK butchered this episode on C4 and E4. When I first watched it, the plot didn't make as much sense. It didn't make sense as to why JK decided to suddenly tell CK that he wasn't human. The UK version cut the scene where Clarke shoved his hand into the woodchipper in anger and asked JK why he wasn't hurt. The UK version cut to a later scene where CK was wearing a shredded shirt and flexing his hand as if in surprise. It was only when Network 2 (an Irish channel) showed it that it made sense. There may have been other scenes cut as well. There certainly were in later episodes.
For some reason on the second airing, the scene where the trucks were stacked in the parking lot was cut.
I think alot of stuff was cut because of length, when this episode originally aired it was 8 minutes longer than any other episode.
The pilot episode is available on DVD for sale at Amazon.com. It won't be sold in stores in the U.S. however, just in Canada.
Electric-kryptonite-scarecrow boy goes on the standard killing rampage against those who had persecuted him, but why does it take him 12 years to do it when all the other meteor-rock freaks have taken care of business at the first opportunity? 
Either his powers developed late, or revenge truly is a dish best served cold...
I thought it was rather ironic that Clark seemed to make a big deal of the fact that the "scarecrow" (I can't remember his name) hadn't seemed to age at all since the meteor shower, while all that time Jonathan and Martha Kent hadn't aged a day either.

Well, I'm pretty sure the fact that he was in a coma for those 12 years had something to do with it.
I, uhhh, must have missed that aspect of the plot... heh, heh.
Well, it was gone after about a second and a half
