Co-signing what TKA
said. Toyotaro's adaptation may not be purely Toriyama, but given how extensive and well-documented his involvement actually is with the manga as a whole (from art and storytelling to gags and even minute details with characterization) in addition to the idiosyncrasies present in the writing, I'm absolutely certain that it's a much closer approximation to Toriyama's vision than the anime tends to be.

A magazine ad for the movie also specifically credits the manga for the form's debut under Vegeta, so I have no clue why people feel the need to downplay its role as an exclusive influence there.
Count me in the same boat. Toriyama's obviously going to do his own thing, and this film should be no exception. There's no reason to suggest that he based the film off of the manga's version of the events.
However, it also warrants observing that, outside of the now three films, there is no "Toriyama's version" of these stories. His unpublished production notes and guidelines are not stories. Based on what we know of his involvement with the manga, and what we know about the film, we can make an inference to the best explanation that, were we to choose between the two actually available and realized stories that cover these events, the manga's are probably a better (read: not perfect or 1:1
) representation and manifestation of what was swimming around in his head while coming up with the story of the Broly film. In this sense, the manga's story would probably better prepare someone for the film's story than the anime's story would.
None of that entails that the anime is bad, or that watching the anime leading up to the film is un-viable, or that there's somehow no way
he took any ideas from the anime, or anything like that. Not sure why acknowledging any of this strikes such a large nerve for some people. If it's because the fandom is so collectively high-strung and tense over excessive, toxic, "Manga vs Anime" flamewars, then it's probably worth taking a break from Dragon Ball discourse online. It's done wonders for me.
