I think the disparity is due to "free movie" vs "another movie". I'd bet Golden Corral gets decent reviews from people who frequent it, but not from food critics.
Bright lost me from the start. If you watched it because anything Will Smith is "great", then you had your mind made up already. Honestly since I didn't see the entire movie, not even more than about 15 minutes tbh, I can't say it's horrible but it starts off horrible with cardboard acting and "been there, done that" feel with Smith. The "oppressed because they are different" theme was thick even early on. I get that Hollywood has to toe that line, but trying to weave ethics lessons into entertainment often spells disaster, especially worn out "think like this" attempts. You see it today in so many films. You just know if there's a hot girl in a lead role, she's going to have a lesbian encounter. She's going to have a friend who's full blown lesbo, and have an interracial relationship. I don't care about any of that individually, but it's become almost a staple in modern films. Even the Brad Pitt movie "Allies" had a sexual relationship, openly lesbian... that would never have been tolerated in that time.
This kind of morality funneling is annoying. It's like watching Sesame Street for adults. It s up otherwise decent films.
