I don't feel super strong about the character one way or another, but I think there is a lot of room for potential with him. He's a genius (sure the MCU has two of them between Banner and Stark but a third one won't hurt), the king of his own country, his powers come from a magical herb, etc. In the right hands, there's a lot of good stories you can tell with the guy. The suit though? As you see it in the movie? Looks bad ass. Hopefully they really do the character justice.
Also, in case you didn't catch it, that was Crossbones giving Cap a knuckle sandwich at the 1:57 mark.
