Well, his secretary could also fight and I don't think Pepper Potts is a bodyguard. The point is that its an MCU show, there needs to be action. It doesn't have to be fancy, but it does have to be interesting. Shows with half the budget could easily show off super strength. Its arguably one of the easiest powers to show on TV. The fact that JJ didn't is embarrassing. There is nothing about being a "character drama" that precludes action. If you badly written drama without action, don't make an MCU show. With such rancid writing, the action should have been an element, along with David Tennant, that helped the show. Instead, it made 70s Wonder Woman look like Arrow.
Hopefully Defenders fixes that. Have Jessica actually punch someone, or hurl a huge table or something. Anything to prove she is anything but a person of average strength who just happens to be good at jumping and shoving. Luke Cage got saved by his show after JJ completely misused him, so maybe she can be saved (from an actionb perspective, no one can fix the broken mess of a character) but Defenders.
