Mediocre and rushed. It wasn't terrible, but a lot more effort could have been made in the script and the action. I watched it despite not being a fan of Millie Bobby Brown, and surprisingly my biggest disappointment was the terrible dialogue and predictable story that they couldn't even make detailed enough to make the movie interesting. No range of emotion in the characters whatsoever. A lot of the same thing happening over and over again. It was so rushed that it felt like a lot of movie for a very short story. It may entertain young children, but not adults.
