Yes, it doesn't need to be rated R. The main reason the first two were was because of language.

Idc as long as it's good.

They didn't tone down the violence in the original 2, so I don't think so. Near as I can tell, the only reason Deadpool 1 and 2 were is for sexual content...

We don’t know.

I don't think a rating matters on a movie as long as it's good.

Honestly, I'll be surprised if the movie even happens with all the conflict it's had

The movie is all systems go now, the guy who directed lovecraft country is directing now, and mahershala Ali is writing now.
