Bio Broly, the final Z movie containing him is by far the worst of a shitty batch, and genuinely one of the worst action moves to have plagued my senses. There is pretty much nothing I liked about this movie, and many many things I disliked. It really looks like they ran completely dry of any semblence of an interesting idea to put here. Our cast in this movie is boring, and I didn't like the treatment of any of our characters. This movie does not look good, and it has no memorable soundtracks.
The plot is somehow possibly the most braindead yet. Mr. Satan is blackmailed by a kid he fought and beat back in summer camp, and threatens to reveal the fact that Satan wet his pants as a child. To stop this from happening, Satan travels to an Island where artificially created bio monsters wait to jump him. Tagging along is Android 18, who wants money from Satan- along with Goten and Trunks.
Here's the twist: The shaman from the village that Goten and Trunks saved last movie has retrieved DNA from Broly's body and managed to resurrect him into a literal walking steaming pile of yellow shit. Why, you might ask, did this wonderful character make a return for revenge? His entire motive for doing so is because Goten and Trunks stopped the Shaman from sacraficing the village kids to the dinosaur. Brilliant.
The fight itself is really boring, apart from a couple moments of Goten and Trunks teaming together. Android 18 doesn't really do anything, and has to be saved by Krillin. They defeat Broly by splashing him with sea water. That's his fucking weakness. THE FIGHT TAKES PLACE IN THE MIDDLE OF THE OCEAN.
Terrible movie, I don't see how anyone would enjoy watching this. Not reccomended.
