Yep, that's the show. I had already become somewhat attached to one of the new leads before I even knew he'd be a lead, and it didn't take me long to become attached to the next, and then the next. . . .

I never started Lost (and several other shows) because I didn't start at the beginning, and I quickly heard what happened to their casts.

I've quit watching a couple of shows because they took the characters everywhere they could take them and then just ... kept going
I'm thinking of giving up Psych because they have a severe problem this way. I've been with them since the start, but the magic is gone.
