A movie doesn't have to be "cool" to being good in plot and characters. And Dead Zone best movie?! Really?!
REALLY?!
I don't have to say much more. Dead Zone, excepting for the animation, is one of the shittiest Dragon Ball Movies ever. The backstory between Kami and Garlic was good, but the execution was lame and schizophrenic.
I feel you didn't read the rest of my post. I mean, I made some reasoning to why it's execution isn't bad at all. Your assertions are loaded but I would like evidence to why it is "lame and schizophrenic." Am I wrong in my belief in how they used imagery as a motif to explain plot within 45 minutes because there wasn't time to go into every little detail? Do you think the "love triangle" that brought all the protagonists together executed poorly? Is Goku actually portrayed more accurately in Dead Zone than most if not all other Toei movies?
Hey, maybe I'm wrong. But, I hoped for a more elaborate post. It feels like you had a bit of a knee jerk reaction to my thesis in why Dead Zone is better than BoG in moving its plot and character development.
The only problem I have is the Gohan scene. Even then, it's actually hilarious. He got drunk/high, and I feel the animators just wanted to show off their skills. It's fun all around and a good break from the seriousness of the movie. You can't have DBZ take itself too seriously. I find the Gohan scene in World's Strongest to be out of place, but not Dead Zone's scene.
The art, the fighting, and even the plot was all entertaining. To me, there's very little cons to the Dead Zone film compared to all other films. Dead Zone has cool and interesting villains, great choreography, well set-up tension, memorable music, a less is more plot, and its focus isn't just on Goku, it is on everybody. Everybody in the film has importance and reasoning to be where they are.
BoG's fight with Goku and Beerus even feels like its trying too hard to be "cool." Goku does this weird glance as he slowly looks up (the camera at a low angle, just to try to show that Goku has become more cool and powerful) and the insert song starts playing... it's so cliche and full of cringe. Compare that to when Dead Zone uses the Makafushigi Adventure melody in the last ditched effort to take Garlic down. That was cool, partly because of musical nostalgia. See, Dead Zone didn't have to directly tell the viewer (ala insert songs during a protagonists "badass moment"), but uses the power of memory to show how far Goku got (and even allying with his worst enemy too). In a sense, it is a ironic motif since the final, end all be all, villain of the original Dragon Ball
was Piccolo! t's so clever how the Toei staff used that irony to highlight the "this is it" moment for the protagonists, who were both Goku and Piccolo by the time that scene in the film commenced!
Since when do chronological errors mean a DBZ movie isn't any good? It takes place in a different continuity, there, fixed.
Even as a side story or a spin-off, why isn't that acceptable? Why does everything have to fit in continuity? I find that notion strange. Why can't there be a story that has nothing to do with the main continuity? If people are that anal, pretend it happened in another universe. I find that a movie, or a special, doesn't have to be apart of anything and can be a standalone story with the main characters from the original continuity it comes from. The movies never claimed to be apart of the main continuity... so what's the big deal?

My favourite art style (and animation) outside Toriyama who worked on Dragon Ball: Katsuyoshi Nakatsuru, Masaki Satō, Minoru Maeda, Takeo Ide, Hisashi Eguchi, Katsumi Aoshima, Tomekichi Takeuchi, Masahiro Shimanuki, Kazuya Hisada
