Can't wait to watch it next week. Just saw apparently the 3rd one is coming out in less than a year which is crazy since we waited like 5 for this sequel.
I don't think the original was planned to have a sequel? Just prepare for this one very much being the setup for a next movie. It was really good though!
I just watched the original for the first time after seeing the sequel a couple days ago. There is an end credit scene for the first movie that 100% sets up the sequel (spoiler: it shows Miguel and the computer chick setting up the first intentional interdimensional jump.)
