Will admit, I do find it a little weird that this movie's premiering as a Netflix exclusive instead of getting a cinema run like the previous films (Also mainly because some of the last few anime-based films that hit there as a 'Netflix Exclusive' tended to be just the teeniest bit dire - I'll just leave Death Note and Fullmetal Alchemist as examples, there, not comparing it to those two at all, just saying XP), but I'm sure they've got their reasons for doing this, and it'll hit a wide-enough audience.
Also nice to see they got Dan Green back to reprise Mewtwo, so that's a bonus in itself.
