Saw Dungeons & Dragons: Honor Among Thieves today with my family (amazon prime early preview). We liked it. Jokes were funny, dialogue was decent (some of it was excellent,) characters were good. There was a cool "cameo" for fans of the D&D cartoon from the late 1980s. It felt like they kept pretty true to the D&D world.
I'm not saying it was perfect but it was fun. My high school age daughter, who plays D&D with friends, said it is her favorite movie. She liked it way more than Free Guy. It's not Lord of the Rings, but it is a fun, light-hearted, fantasy genre movie with decent action.
BTW: There is a short mid-credit scene after the movie that is worth the wait.
