The first Purge was too insular on one family who continuously fucked up throughout the movie. I hate comparing the Alien series to the Purge series, don't think it's a fair comparison since I thought the Alien series was mostly done right and the Purge series was produced very sloppily with a poor director.
If the hypothetical idea of an afterlife means more to you than the objectively true reality we all share, then you deserve no respect.
