Eh, I've noticed a lot with these superhero movies is they are heavily dependent on the quality of actors, despite being mostly about special-effects. Even if real acting is only relevant in 15 minutes of the movie, those 15 minutes are absolutely vital to making us care about all the combat and superpowers in the rest of the movie. Gadot is a mediocre actress. You can tell even in the cherry-picked brief little monologue of the trailer. She sounds flat as fuck, nowhere near as epic as, say, Patrick Stewart making a little Xavier speech, or the equivalents in any of the more successful superhero flicks. She just doesn't have it. She's a model pretending to be an actress.
