I mean, I can't waitttt to see this... but seriously, just go the next day if it's sold out. Jesus.
I'm glad I work shifts, and often have Thursdays & Fridays off so can just go in the daytime. My friend and I always go about 1/2pm the main day big movies come out, never have to prebook anything, there's always loadsa room. All the kids are at school and most people are at work

(and also can't stand busy cinemas, esp on a weekend evening, vastly increases the chance of someone talking, using their phones, people constantly getting up and walking in and out to use the bathrooms, some big head right in front of you blocking half the screen, etc)
