Beyond this, there isn’t much of an emotional point aside from Deadpool figuring out what it means to matter
This reviewer seems to be, perhaps intentionally, missing the point. The movie's "emotional core" is, fitting for Deadpool, a metanarrative one. This is the end of the Fox Marvel movies. The cameos and references are not just there for the fun of it, but they feed into the point of the movie. It is giving people some kind of closure to characters and movies they grew up with. It is saying (at one point literally in dialog) that the past, even with its mistakes and missteps, makes you who you are. It is a celebration and a sendoff of a bygone era of superhero movies.
Perhaps the giant ruins of the Fox logo were too subtle.
