GotG2 will suck. Not horribly, but... yeah. Hard to repeat what happened there, I will bet. Oh, it'll do ok at the box office, but be not nearly the sensation.
Captain America 3... I have to see Winter Soldier, but likely that'll be a mainstay, and do well.
Thor 3 will.. do okish.
Black Panther will rock, watch, and do quite well indeed.
Captain Marvel will do... admirably, but not as well as hoped, I bet.
Inhumans will beat them all...
...until Avengers 3 shows up. But Avengers 4 will be like Matrix 3, and disappoint, finally ending the series.
Doctor Strange, if Cumberbatch is named, will then BEAT THE SMITEREENS OUT OF THEM ALL BECAUSE CUMBERBATCH, and you know of his legion of fans, right?

These are but a guess, and I don't hold any true expectations of being absolutely right. I look forward to seeing how I did. What year do I have to live for to see the results? 2025? :p
