Wow. Now that is seriously overkill. Even five films was kind of pushing it, but eight movies is way too much. I haven't even seen the second or third Shrek films and I don't plan on doing so. I did see the first one on television once and it wasn't a bad movie. I just thought that it wasn't that good for all the hype it gets. Besides that, it felt that it could have ended right there without all of the sequels. I agree with you on how a television series would work out better than all of those movies, especially with how they'll run out of reused jokes and pop culture references for each movie.
It's too bad that their movie called How to Train a Dragon was pushed back to 2010. It sounded like an interesting movie and I would have actually gone to see it, instead of waiting for it to come on television, mainly because of I how I really like dragons. Plus, it sounded like it would be something more worthwhile to see than another Shrek movie.
