So bad. So, so bad. I tend to poo poo the critics, so although the RT score was worrying, I went into it figuring the Rock would carry it. And the Rock was good as the actual character. The actual movie was just baaad. The exposition was about as cringeworthy as possible. The introduction of the "antagonists" was cringeworthy, as were the actual "antagonists," save for the girl. There was a lot more I didn't like, but I don't have the energy to get into it.
Now, this wasn't WW84 level bad. I would say it's Aquaman level bad, where it was just clunky, hamfisted, but not "oh come on, how idiotic can you be" level bad. I hold out hope that the sequel/sequels might be better, but we also know what one of the worst DC movies was, so...le sigh.
