Its the arragance I hate... "I'm so fucking deep and thoughtful, look I've sat down and planned this epic 3 part story..."
No mate, your films stupid, and your stupid! There's nothing deep and meaningful about it to warrant a trilogy. Blade was dumb, a sequel was warranted and made, but the fact its played out as 'an intended trilogy' is just stupid imo, its like why 3? Why not 4? Why not 51 so you can dump all the unsold copies in 51 landfills in 51 states.... what a tit!
But every hollywood hack thinks 'yes i'm sooooo deep, look I've written 3 scripts instead of one", just because some great writers have written some great trilogies/epics in the past. Sad really.
Perhaps, and rightfully reserved, a trilogy must mean 3 continuous and clear part movie franchises. IMO. Alien is a trilogy, it sure wasn't planned that way, but the 3 movies in their own right showed a full cycle of a character which is much deeper and the films are clearly linked. That's trilogy worthy. The original Star Wars films, that did a full story, a full circle, a begining, middle and an end. LOTR is a trilogy (of six books but its the clear, 3 parts).
Then again, the Matrix is unworthy of being a trilogy... it just so happened their were 3 instead of the 2 there should have been. The first was 'great', so a sequel was warranted.... but there should have only been one. Then if that was successful, another. Austin Powers isn't a trilogy... there's just three of them made. At least they don't claim its a trilogy.
Nowadays everythings got to be a f*cking trilogy and its pissing me off, Xmen... oh no its another freakin' trilogy.
It's just arrogance of the film makers, they want to appear all big and clever... I think that's what it boils down to. Hollywood has always been like this though... just something that pisses me off. Oh and if trilogy isn't enough to make people feel big and important, despite the lack of talent, now Fox has invented some crappy Quadrilogy word. No Mr Murdoch, there's just four of them... and your a tit.
