I live pretty close to my local theatre, say a 5 minute drive if that should traffic allow.
I typically like seeing movie trailers before a film so I don’t mind a little padding but the commercials before hand are ridiculous.
Back to my point, today I went to see Whalefall and incorrectly remembered the start time, I thought it was at 1:30, it was technically a start time of 1:20. I left my place at 1:20, got to the place at 1:30, parked, had my tickets scanned, and walked in to the theatre and we were perfectly on time to sit down right as the feature was beginning.
So it’s a good 10-15 minutes of front loaded crap before the actual movie starts. And that’s if you get there right at the supposed start time.
