the early reviews being mixed is not an opinion that you can disagree with. you can disagree with the critics's opinions on the films being good or not but you can't pretend that the critical reception is something that it isn't and you don't need a critic to validate your opinion of a movie anyway.
besides there are plenty of great movies with mixed reviews so I'm not sure why that's an issue. (Aquaman, Joker, Aladdin, Alita and IT Chapter 2 just this year).
