We have stayed there during our last two January trips and plan on staying there again this January.
It is by far the most "Disney themed " resort. It is what it is.... a value resort. Clean, the basic necessities, and a place to lay your head. If you plan on being at WDW for the parks, Movies is the place to stay. If you plan on doing more things around the resort, you'll probably want to look into a Moderate or Deluxe.
The buses are not bad if you have patience. Most of the time we never waited longer than 15-20 minutes. Typically for the MK and Epcot buses it was around a 5-10 minute wait. We have never had a problem with the noise (we stay in the Toy Story Building). There does tend to be tour groups, but they have never bothered us.
Honestly, we could stay in a cardboard box, after all we are at Disney World
