The document summarizes Glen Munro's list of the worst movies of 2017. It includes 10 movies or trends that disappointed him. The #1 worst movie was Valerian and the City of a Thousand Planets, which had amazing visual effects and a large budget but lacked chemistry between the two main characters. The failure of The Mummy movie caused Universal to shelve plans for other monster movie reboots. The author hopes to have a hard time filling out a similar worst-of list in 2018.
