The only Marvel movies we haven't seen yet are Captain Marvel and Avengers: Endgame. We've LOVED all the Avengers movies. We just don't bother with the theater anymore. We wait for them to come out on disc and watch them at home. We did try the different series that were on Netflix and for whatever reason, just didn't stick with them. We probably watched Daredevil the most. Jessica Jones was really good and I agree that David Tennant played an awesome bad guy. I can't remember why we stopped watching. I think it was a really long time in between the release of seasons?
We've seen most of the X-Men movies, except the 2nd Deadpool and the newest one out now, Dark Phoenix(?). They can get a little confusing with the reboots, and timey-wimey changes. We enjoyed the first Deadpool, but it just didn't feel like part of the overarching story. And we HATED the last Wolverine movie, Logan. It was a travesty.
