I think they handled the Sharon and Steve stuff well. For sure there was a spark of something in TWS that we saw grow here. For the love of Stan Lee, we saw that Sharon was willing to put her life on the line for Cap in TWS during the hellicarrier launch stand off. The film had a lot on it's plate and while it would have been nice to see some more Sharon I think there is enough there to indicate the START of something. That's just it... Are people not aware that adults kiss all the time? Yeah, shocking I know, but people kiss people BEFORE they are in total all consuming, let's get married and have six kids and live happily ever until we die on the same day LOVE. These are the tentative steps of mutual attraction. Yeah... Sharon also has a part in this you know. It's not all one sided with Steve in the drivers seat some how controlling Sharon. There's was obvious attraction in TWS and now it's paid off in the baby steps of the start of something.
