The action scenes were fantastic. The acting was good as always in the MCU, Don Cheadle and RDJ are amazing of course. Black Widow's introduction is great, posing as someone showing her hidden background. This film isn't bad, and definitely not the worst of the MCU, it's just not as good as some others. The problem with this film and some others, is that the villains are terrible, some people don't even remember them, of course I do because I just love marvel but still, the villain's story really isn't that good, and with Whiplash being a character introduced through the movie, not even die hard marvel fans knew about him at first, they knew about his father, but not him. Overall the film isn't bad, just one of the worst of a great franchise.
