I finished the first three seasons of Smallville some weeks ago. The Clark and Lana romance subplot really dragged this show down. I liked it in the first season, was okay with the second season mostly, but by the third season I was really sick of the “Clark has to lie to protect his secret, Lana is super mad” dynamic. And I knew Lois was going to appear in this show, so it was especially annoying seeing a doomed relationship be dragged on. And this is apparently Lana Lang before her character derailment.
I’m not so interested in seeing the later seasons largely because supposedly it has less to do with Clark’s adventures with Smallville (though to be fair I think I’ve seen enough of that) and moreso a Superman story where he doesn’t wear the Cape.
