Black Widow's trailer is...trying way too hard to get people to care about a character that is pretty much done in the MCU.
Movie is like 2-3yrs too late, if this came out before they killed her character off, maybe people would have cared more about her dying, but honestly I don't think anyone really gave a shit her character died, I kind of laughed at the whole scene because it was like "Oh...ok, I guess Woke Lame Hulk will find another love interest."
Only thing I am looking forward to in December is The Witcher series.
