It's good to hear that this movie is working more with the premise of the original. However, a chunk of the laundry list Bob mentioned in the beginning could be explained by a combination of precedence and time. The first Purge had people who weren't sure if it was "really a thing", so they stuck to petty crimes like blatant littering, recreational drug consumption, mass streaking, and other things for the lulz. When the reports of murders/rapes/embezzlements come in and no one gets punished, the next Purge "gets real". Homes gets better security, people get self-defense/firearms training, and the "poseur" Purgers don't want to risk coming across Purging enthusiasts who're trying to fit their crime wishlist in a 12-hour window ("Graffiti? Seriously? Ugh, amateurs." *chainsaw*). With a few more Purges under their belt, people start taking pride in their "civic duty".
On that note, I like the idea of having different Purge films have different themes. Since the movies are relatively inexpensive and can more easily recoup their investments, it could expand into a multimedia franchise. Have a revenge arc for a YouTube series, political thriller for a podcast, quirky post-Purge cleanup crew as a dark comedy, and save the movies for the gritter/complicated setpiece moments (bank heist, suburban riot, gang warfare). Then again, it'd risk being oversaturated, so it'd be a balancing act.
