LOST is a great show, despite my ex thinking it getting to bogged down. She was down on it before we broke up and when we did "lost" interest in following it. She says she is done with it. However, she loved s2 of HEROES and thinks people are overly harsh on it.
Ironically its her S2 set I'm going to get tonight
I shall not compare or contrast the two until I've at least watched s2 and started s3 of HEROES.
