I was fully entertained throughout, but I get the 25% rating.
The film felt very too quickly paced and it had a Family Guy "listen, it's time travel, try not to think about it" vibe.
It also, humorously, does a great job of not understanding current technology in its effort to show us future technology.
I loved the nods to the original film, but they spent way too much time trying to force this to have charm through comedy and it usually didn't work.
