I predict that Captain Marvel will be the new center of the MCU post End Game, they will focus on her for a while, but won't do any major team up movies for a looong time. There will be team up movies, like duo's maybe trios, but not major multi movie multi character arcs.
Will be really hard to top End Game, so no point in trying until we are craving more.
In Hellboy news, I did not know that it got a R rating.. this is kind of cool. I still just have trouble accepting a non Pearlman Hellboy, and this trailer does give away a fair amount of the movie.. but I am more inclined to watch it after this trailer than the first one. Redband trailer, NSFW language/violence.
