I would say it would depend on how picky you are about where you sit in combination with the area in which you live. The film is raking in gads of money, which mean selling lots of seats lots of the time. I'm sure some communities walking in the last minute is fine -- and others you will be stuck in the front few rows.
I know when I saw this the day after Xmas, a 1 pm show, there were many people that couldn't sit together because of the time they got there. This is the first film in ages where I had no empty seats next to us -- and we see a lot of films their first week out.
If we're not having fun, then why are we doing it?
