Decent watch at best, probably won't watch again, but can recommend for younger audiences.
This franchise just keeps getting weirder as it goes on. Almost like someone is making bets behind the curtain about whether or not they can get away with things.
I'm the first person to get onboard with a "stuck in a video game" trope, but they made some really weird choices that offset it. The inclusion of big celebrities that kids won't recognize is a little odd, but the in your face 3-d stuff is irritating, and there were several forced scenes, and a conflicting message of competition vs cooperation.
There are really high points of the movie: the story line itself is actually pretty good, the robot battle detour was actually a fun way to set up a call back, and there is a really good, if short, twist that I wouldn't expect in a kid's movie.
The last act was a little too insane for me, but I'm thinks kids might like it.
