I am really looking forward to it but I am a bit disturbed at the level of negativity I have seen online.
Many people are saying that Bucky should have become Captain America, which seems so strange to me. A man who assassinated the most beloved president in history should become the symbol of America? But of course, Bucky was brainwashed when he did this - I don't see how telling the American people that you only killed their favourite president because you were brainwashed by the Russians would be deemed something in the plus column on his job application.
Then there is this obsession with Sam not being a super soldier. At the very core of Captain America is the notion that it was NEVER the serum that made Captain America. I don't know how many more times they can possibly repeat this before it sinks in. Some people ask how Sam can even throw the shield without super strength, which overlooks that, in the comics, the super solider serum DOESN'T provide super strength (that's the Power Broker treatment), so Steve Rogers has been hurling his shield with normal human strength for over 50 years.
It's odd that so many people clamouring for the return of Steve Rogers don't seem to believe in anything he actually stood for.
I stumbled across this, which I think covers off what the writers have been trying to convey:
Most of all, I am looking forward to seeing Diamondback. She was Steve's sidekick for about 10 years in the comics and it would be nice if her story could form part of Cap's story going forward, especially if Sharon is a bit of a grey character for now.
I fully expect Steve Rogers to return as part of the Secret Wars saga, possibly recast as part of a soft reboot. They squandered Red Skull and Crossbones so far so, in the meantime, I hope that they can world build a bit more and not let Cap's own universe be subsumed by the Avengers. CA: the First Avenger and CA: Winter Soldier have been the only proper Cap movies to date. I'd like to see more like that. Maybe even a TV series based on the Bloodstone Hunt.
