Maybe 3 isn't the magic number?

In yet another one of those "stupidly-random-self-realisation" moments (I get these far too often), I happened to notice that, on average, by the third film, everything in the storyline has gone to shit.
Ever noticed that? Here's some examples:

• Lord of the Rings 3 - Everybody goes to war
• Resident Evil 3 - Full blown global apocalypse
• Star Wars 3 - Nearly all good guys killed
• Pirates of the Caribbean 3 - The government owns the seas, everybody's against one another
• Spiderman 3 - 2 enemies at once/everyone hates Spiderman. Again -_-
• The Dark Knight Rises - Not out yet, but the trailer depicts a Gotham falling apart. Again -_-
• Transformers 3 - Full on, blown out global Robot Wars!
• SAW 3 - Yes, I know everything's morbid anyway. But 3 is a lot more gorier than 1 and 2, and then the gore levels just kept rising
• Jaws 3 - Is shit. The 3D attempts are hilariously appalling
• Austin Powers 3 - Recycled jokes, flat storyline and a pathetic twist. Or is that just all of them?
• Ice Age 3 - Apparently 'Ice-World' lives above a hidden dinosaur community
• Toy Story 3 - All favourite characters thrown out of home and locked in a day care centre. Yeah, not the worst one so far, but hey!
• Shrek the Third - Is shit. End of.

There are probably others; I could go on all night. And would, if it weren't for a fear of boring you.
And before anyone points out the obvious, yes I do know that some film series don't follow this rule, like Harry Potter 3 for an example. Although after 2 and a bit hours of Daniel Radcliffe's wooden acting, it may as well follow this procedure.
And then of course, there are films that are shit by the second one - Night at the Museum, George of the Jungle, the new Alice in Wonderland.....They're either crap, or within them, everything's gone to crap. Oh the joys of the film world!

Anyway, just another random chapter in the book of my life. I think one day I'll write the blurb for that book. It'll be something simple like: "Good luck".
Right. Peace out! =]
