We watched Mulan and WW84 the past few days.
WW84 had cool visuals/eye candy, but the story itself was so blah. I also didn't really get how she could swing from lightning bolts or fly now, but some things like the invisible jet and and young Diana scenes were pretty cool. Loved the cameo at the very end as well.
Mulan was excellent. Great storyline, well acted, super cool visual effects throughout the story. My only complaint is that the regime pretty quickly moves from "women can't fight and will be killed if caught trying to join the army" to "Yeah Mulan is a girl, but she should lead us," but that's just part of the magic of Disney. Great family movie if you're looking for an alternative to WW.
