Wonder Woman did have it's serious moments.She fought Nazi's.It was kinda serious.I did like the scene at 8:45 where she had a genuine conversation with her mom.They talked about being WW with touchy music in the background.
Probably better than humans.Amazons are depicted to lift boulders and fast as animals.There are no where near Wonder Woman's level.Some amazons can be picked to be a powerhouse.Wonder Girl got to be a powerhouse.
Villains don't have to be morally grey to be interesting.Look at Batman's villians,most of them aren't grey area villains yet he has the most interesting rouge's gallery in comics. They're either crazy,bored,hate batman, or insane.
Bands are really not worth the effort, money or time. They are little better than isometric exercise and you will plateau quickly and under a relatively low load. Free weights are most efficacious the least amount of time; weight machines are safer than free weights but not as effective for gaining mass (hyperplasia).
I'm not looking to gain mass.I'm a long distance runner.
