It needed a bigger budget
I liked the movie. I thought it was a nice comeback for Pee Wee. I can understand them not giving the movie a bigger budget, cause you didn't know if there was a big enough audience. Hopefully the movie does well and the sequel will have a bigger budget. You can tell the wanted to do more, but was forced to scale back.
My only other compliant is that the secondary characters needed to be better. They were fine, but I was hoping for better cameos.
