This was kinda great, wholesome fun and pretty cute, although sometimes it tries to be too cute. :P
The animation style and rendering is as fascinating as it appeared to look in the trailers. A flat out great looking, visually-inventive movie going at 100MPH at all times. Only grip I have is it seems they added a film grain filter at the last minute (it's not in any of the trailers), makes the movie look unnecessarily a tad grimy, and I think might be responsible for the colors not popping as much as they could. It's also only 1080p on Netflix for some inexplicable reason and I'm not sure it was graded for HDR at all. I assume Sony still has the rights to home video so maybe they will do this movie right eventually.
You know, Sony Pictures Animations puts some really great, creative stuff out there sometimes. More often than what some of their big-time competitors do if you ask me!
Selling the film to Netflix might have been shortsighted since it turned out great and it seems theaters are finally making come back but it was the safest decision back then I guess.
