Murder Mystery 2. It was pretty bad. It seemed mailed in, with barely any jokes that landed and a generic plot. Even as a time waster, it wasn't really worth watching.
Shazam 2. I had pretty low expectations, but I thought it was more entertaining than most recent super hero movies, particularly from DC. My son usually has a hard time sitting through movies, but he commented that the movie seemed really short. It wasn't -- it's around 2 hours -- but I think he means it was well-paced. Most of the actors are pretty charming.
John Wick 4. Do you like John Wick movies? If so, you'll like this one. I'd rank this one closer to JW3 than JW2, which means the difference between good and very good. The plot is very thin and, as you may have heard, Keanu has barely any dialogue. The stylized violence is non-stop and very polished. The movie probably could have used some room to breathe -- they reportedly cut 45 minutes from the film, mostly of dialogue -- but if you're up for pretty non-stop action, it's definitely there.
