How'd I miss this thread.
If you haven't just gone ahead and downloaded some fansubs of all of the movies, you're a fool. BUT:
I could never get into the movies too much, for probably the same reason I couldn't get into the series after a certain point. Fuckin' Goku is always Mr. Savior. Fuck that. I kinda wish the series had ended after Frieza was killed off (the first time) and allowed the movies to take on the rest of it. I'll talk DBZ with someone all day, but FUCK do I dislike the series more and more as it goes on. And am I the only one that prefered the original FUNimation music and voices over the ones that took over from the Ginyu Force fight onward? There are natural advantages inherent in the real dialogue and whatnot being used as well as people being allowed to die ("I can see their parachutes! They're okay."),but the shit sounded cheap as fuck.
Best of the movies: A tie between 6 and 12.
My personal favorite: 2, which took place during what I consider the series' peak.
