Movies has the best food court. No 2 ways about that.
Theming is all up to personal taste.
I prefer the bus service at Movies. Here's why:
When the 3 resorts share a bus, Movies is the last to be picked up. Some people complain about this, but seriously, wouldn't you rather just be picked up and head directly to the park as opposed to being picked up and making 1 or 2 more stops? Plus, if it's ever so crowded that there's only standing room left, they will send another bus soon after.
Let's say you're leaving the Magic Kingdom at closing. It's packed. You're staying at Movies. You get to the bus area and the line for the Movies bus is long. The line for the Music bus is short. Just take the Music bus. The walk to some of the rooms at Movies is shorter taking the Music bus.
You'll notice, at super busy time, all 3 have their own bus. At busy times, Sports and Music share, while Movies has their own. At slow times, they'll all share. Overall, Movies is your best option in terms of bus service.
