Pretty bad.
Bad story, bad casting, bad acting. Falcon is awesome in the movies. He competent, witty, and played well off Steve Rogers. Here he is lame. From the movies everyone knows he would be a great Captain America. Here you almost have to question it. What happened to Sam as a character? A storyline where Sam cannot get a loan?? Seriously????
The flag smasher group is horrible. Bad casting, writing and acting. Just a bunch of bratty teenagers. Imagine an entire group of prequel Anikins. These villains are no Loki, or Obadiah Stane or even Justin Hammer. Actually, Justin Hammer was a better villain just for the way he calls Tony Stark "Anthony". Seriously, one word is better than the entire Flag Smasher cast.
Zemo was by far the best part of the show. Amazing what a real actor can do.
Bucky has a sub plot built around redemption, that is better than the actual story. It's not great, but it beats the main story line.
If your definition of good is Iron Man 3, Thor Dark World or the villains in an Ant Man movie then you will like this.
But it's a huge step down from any Captain America, Spiderman, Iron Man 1, Avengers level movie.
So disappointed.......
