When He was introduced he was actually a very powerful character to be feared and he could fight an entire crops by himself. Now he is just a joke (A bad one at that) I hate how they turned him into that.
It really does take away from the story and sometimes the future story. Like when Cap died I was furious but I very quickly learned to love Bucky Cap then of course even more quickly they brought back Steve. I always felt cheated that we didn'y get more time to see what Bucky would have done as Cap.
