I started watching in 2006 I think. My housemate at uni had all the seasons that were released on dvd and we watched it while eating dinner, usually a few episodes a night. Didn't take us long to work through the first 6/7 seasons.
And then when we caught up with the show we watched them weekly.
Because we watched the first half of the series so close together it's a bit of a blur (
) so I can't really pinpoint what really grabbed me, but it's a good show and yeah it has it's problems but you know what you're getting with Smallville
. It's reliable and has pretty people it's been pretty good with DC mythology, especially in the last couple of years.
