Hmm I finally might have a use for my xbox one!
Believe it or not, but i use my xbox one every day! Use it more as a home entertainment system rather than a gaming console. I've got a USB TV adapter, so use it to watch normal tv. Only downer is the TV adapter is not supported in NZ, so you don't get the EPG and have to set your xbox region to a supported country (mine's set to UK). We've got the xbox media remote and everything setup to turn on/off with the xbox, so don't need to fiddle with multiple remotes or the controller.
But back on topic, I do suggest renting a movie using the xbox and seeing how you go. Unsure how the MS movies library compares to others providers (and whether they have what you want to watch), but i guess there's only one way to find out!
