Blue Mountain Mystery is set mostly in a rock quarry, but it still looks terrific on Blu-ray. The animation isn’t close to Pixar or even DreamWorks, but it’s a step ahead of most television or direct-to-video productions. (You can even make out the grainy patterns on the rocks.) A couple of scenes did look slightly blurry at the corners - perhaps a consequence of the running time for the U.S. release being inexplicably stretched from 62 to 64 minutes. There are no problems with the DTS-HD Master Audio 5.1 sound.
The Blu-ray/DVD set includes a handful of special features: two “karaoke” music videos for songs featured in the film, a “hide and peek” game that might be a bit too commitment viewers young enough to enjoy it, and a short but informative feature on the difference between standard- and narrow-gauge railways.
Now that one Thomas & Friends Blu-Ray has made it into my house, I suspect there will be many, many more to follow. Hopefully, they’ll be as good as this one.
