Just saw a 1030am showing in Cambridge England. Every single seat was taken except for 2. Good reception to the film from the crowd.
Personally I liked it way better than Ant Man and the Wasp. I'd put it middle tier overall for marvel movies. Brie Larson was fantastic, plot was generic and way too shallow on character depth. Beginning and ending we're great, middle was ok. B+ for me.
For comparison I liked Aquaman a bit more, Man of Steel a lot less, and BVS and Suicide squad we're trash in comparison.
