Wrong. "Critical success" means jack-squat, especially since it's 250% subjective.
You only say that until it's a movie YOU like that gets good reviews. Just like how DCEU fans kept saying there was a conspiracy against the DCEU and how reviews meant nothing until WW got good reviews and suddenly they were praising those same critics.
Critical success counts, especially when enough of them can reach a consensus. Sure, there can be some exceptions like how John Carpenter's movies were thrashed on entry...but even then critics and audiences came around eventually and started praising them.
