First of all this movie should be emotional i mean i didnt even feel that i lost a great hero, as this movie was made to tribute black widow, but marvel has pretty much failed to connect with us.
They wasted one of the best character Taskmaster in this movie, because the taskmaster can copy any moves and in the future taskmaster could give a good competition to the Avengers, Taskmaster "was" a versatile villain, i really loved that character when i saw in action.
Also the whole movie was not actually focused on Black widow i felt like marvel was just introducing us new superhero and characters and that's where they failed us to impress.
Cgi were also not so good for the movie like this specialy in the ending scenes. I didn't expect it from marvel i'm not even talking about the marvel series which they have recently released had good cgi. From past few years we have seen great movies from marvel with great Cgi but i'm totally disappointed with this specific movie.
I have seen all marvel movies and i can clearly say that this is surely a disappointment actually, even in the fantastic four 2015, cgi were great there. They should have come up with a great story and should have saved the taskmaster and for the red guardian... hhhuh im just sad. I'm not complaining about the actors here they did a great job, just disappointed with the story.
