I'm ok with all of the stupid stuff except for that scene. It's Star Wars, it's fine to be stupid, but "my name is Han and I'm here by myself" crossed the line.
It's worth a watch. Probably best to smoke a joint first, it's not exactly a thinker. But it's a fun movie, and a lot of Star Wars seems to be lacking in fun lately. But be prepared for the cringe in one particular scene.
I really do wonder what might have been if it released before, rather than after, The Last Jedi. I only ended up seeing it because I got to go to a free screening with the new chewie, and it was a fun movie. I think at least on par with the prequels, but certainly more felt more "star wars" then the Sequels.
Fun fact; in the scene where K2SO slaps Cassian while pretending he's a prisoner, Alan ad-libbed the "And there's a fresh one..." line, and Diego Luna immediately cracked the fuck up during the take, but being a total pro he manages to (almost) hide it behind his hand while pretending he's holding his face. Alan's delivery was so good that they kept the take.
