The movie isn’t trash because the good acting from Ford, Lutmby and even Mackie prevents that. Plus the Red Hulk action was great.
The problem was the story.
There is no point giving Sam a half baked unused Incredible Hulk 2 plot for no reason because you want to tell a worse version of Winter Soldier and parts of Civil War.
Sam spends the movie fighting regular men when he could have been fighting gamma super soldiers/Hulks?
Sam was fighting super soldiers in the TV show so why is he fighting and struggling against regular men in a theatrical release?
The movie should have been about Sam reforming The Avengers and stopping a global threat.
