I found them all brilliant when I first watched them...I even went to see the 3rd one the day it came out with a group of tiddlypeeps.....Then I watched them again a few years later and thought "my god this is twaddle"...and now when I watch them I just think it's all pants apart from the big battles, which are all basically interchangeable anyway - "people have big battle with snarly evil goblins, goblins seem to be beating them, then someone else turns up with more people/magic and they prevail in the end to dramatic music."
In fact even the music grates me now...I think it's actually quite shit, and it irks me it's rated alongside genuine classics like Rota and Morricone stuff in all those pointless polls people love having.
Odd really. How times change.
