Lost-the 1st couple of seasons were decent, but it started dragging along and I found myself having it as background noise (missed the final season).
The Sopranos-waning interest after a few seasons/bland episodes. Disconnected HBO before the final season and didn't skip a beat.
The Walking Dead-if this were a mini-series, I might have watched it. Otherwise, it got skipped over after the first few episodes.
The Game-I could tolerate the 1st couple of seasons. Dumb drama killed it off...preferred ESPN's "Playmakers".
Everybody Hates Chris-This was actually a decent show, but time changes and other priorities had me missing episodes...nevermind!
Girlfriends-just for semi-eye candy. Like The Game, I tolerated it, but it'd grate my nerves after a while. Skipped numerous episodes and it got canned...
The Bernie Mack Show-I actually liked the show, but priorities got in the way. The kids would sometimes grate my nerves. Otherwise, I'll catch some episodes in syndication, so it may not count.
I just don't mess with network sitcoms anymore, unless we're talking past ones in syndication...
