If Kristen Bell couldn't keep me watching Heroes, your show must seriously suck.
Alias had similar problems to all these shows, but hell, I managed to watch most of the episodes and enjoy them. One thing Alias had over the other shows was that it was coherent within it's own universe. Lost is incoherent in any universe, 24 breaks it's own gimmick when the show doesn't run in real time anymore. Heroes has people with super powers not use them and act unheroic/emo.
Wait a minute, why the hell are we even discussing this in this thread anyway? Is thisD_Average's Funhouse?
