Amen.
If I don't expect a movie is going tp be good why the fuck would I spend $15 on a ticket? The whole "this is totally going to suck but I'm going to go see it on opening night" bullshit is what's wrong with pop culture.
I always assume DC movies are going to be awful. That way, I don't get my hopes up, only to have them shattered when I actually watch them. And I will always watch them, just to see what they are like. If they are watchable and/or good, that's a bonus.
With MCU movies, I always assume they are going to be good, if not awesome. Thus far, I have not been disappointed.
As for any marvel properties not made by the MCU... I adopt the same criteria as I do with DC movies..
