We really enjoyed this film. Some parts seemed a bit draggy, but overall reminded us of the earlier Avengers and Iron Man films - good humour, good action, good exposition. I'm not a fan of Brie Larson's public persona, so was worried about how she'd do this one. We really liked her witty delivery - some occasional sarcasm, but not arrogant. And Nick Fury's relationship with Goose was hilarious. We liked the 90s nostalgia, and all the extra details/Easter eggs that flesh out the MCU stories.
I get why some people are saying it lacked tension because CM seems infallible, but it wasn't enough to ruin it for us. Good guys usually win in these stories, so it's not like there's that much to worry about anyway.
