Hi Backbay....you're about a week ahead of me and it is still tough to sit for long, isn't it?
My suggestion would be to grab and aisle seat so that once everyone is seated and the movie starts, you can stretch your leg out completely. That might even give you enough room to do little leg lifts and slides to keep it moving. I did something similar to this with my LTKR at about 5-6 weeks when I got back to going out to restaurants.
One other idea that comes to mind would be to sit on an aisle way in the back, so you could get up and move if you need to and not disturb others.
I'm guessing that these ideas might mean going to the movie at an unpopular time so the theater isn't too full.
If you go see any of the movies, let me know what you think of them and if you think it was worth it?
Weezy
