Harebrained plot.. with some good stunt work.. banking more on nostalgia than anything else.. Why couldn't taskmaster take the vials from Natasha's contact.. what was the need to attack her.. She was anyways going to bin the stuff..
Were the prisoners in the prison Red Guardian was held in not allowed visitors, what was the need to break him out of prison in the first place.. they made him useless later in any case..
the whole sequence in the red room was sense less..
