LOST has lost it
I'm sorry to say that LOST seems to have jumped the backwards-talking midget shark. It seems to be the TV show no-one minds admitting they watch, but the formula, which is apparently Twin Peaks but with more writers and less drugs is wearing thin on me, and I suspect a lot of other viewers.
This started to get way too long, so I'm going to summarise:
1. Twin Peaks was, at its best, better.
2. Twin Peaks sucked pretty bad towards the end ... but we haven't seen how much LOST is going to suck yet.
3. At least Twin Peaks ended.
4. There is no way to resolve LOST at this point without aliens, creamed corn, and magic.
Of course the heart of the problem is the economics of TV production in the US. If you produce something and it's successful it is mandatory that it last at least five seasons so that it can make money in syndication. Thus, LOST must run five years to justify its existence, which means stretching out a pretty shaky story for about eighty episodes more than necessary.
