Inbetweeners has gotten a fair few mentions... I kinda like it. That one might be an age thing, a lot of the jokes are pretty squarely on the "teenage" level, the best parts drawing from how people smack-talk each other. I can see where you're coming from, it's not crazy-good, but I get a few laughs out of it per episode (even when it's crappy, it's entertaining crap). Same for Skins - not great, but entertaining enough. For both of them, the first series (first + second for Skins) was somewhat better than the most recent stuff...
Someone mentioned The Big Bang Theory, which I really like. Only way I can explain that one is that a lot of the jokes tend towards the science-geek/general-geek end of things, so if you're missing references then a lot of it would understandably fall flat.
As for Lost, that show was for a long time stuck in a twilight zone of not knowing how long the series was going to be, and hence how quickly they could tell us things and answer the many, many mysteries. Now that they've got an end-date set it's gotten a lot better, and actually feels like they're going to explain things, even if it is still suffering a bit of a hangover from the burden of the weird things invented to pad the show out in the middle section.
Heroes I enjoyed at first, it's gone downhill... remains to be seen whether it can pull itself back up to being good again in the next season. I think I was mostly watching for the Sylar stuff towards the end - he's a great character... shame what happened at the end of the latest season, but from the looks of the preview of the next one, you can't keep Sylar down for long. Trick is to not think too hard - it's never going to make sense, but it can look good doing it.
I don't really have one to add to the list, so instead there's my reasons for liking the things other people don't like. Yay originality.
