This show has gone from filler episodes to rock bottom in a few weeks as i see it.
bringing in doomsday was actually a good idea in terms of closing the whole smallville saga. As he is the only person/thing to actually kill superman in the mythology it is a good inclusion to smallville to push clark kent to becoming superman.
back in the episode where we saw the justice league they mentioned they'd never heard of chloe, at least we now know why....chloe gets killed by doomsday is my guess (chloe is annoying me lately and its time for her to disappear) and i would like to see clark step up for the first time and actually do something. Oliver queen is actually my favourite character as he is who clark kent is supposed to be.
