I still haven't seen Endgame or Spiderguy Far from Home yet, but so far my favourites are Civil War, Ragnarok, and Ant-Lad and the Wasp.
Captain America: Civil War is one of my overall favourite MCU's, just because of the huge cast of characters. The story is underwhelming compared to the civil war events in the games and comics, but it made for a good enough movie plot. My only real complaint is that War Machine got bitch-slapped instead of Hawkeye who I detest.
Thor: Ragnarok was weird but supremely enjoyable. It was a bit more colorful and wacky than other MCU films, but made for fun & different takes on Thor and Hulk, and the supporting characters like Valkyrie were cool. This same director is on board to do a 4th Thor film and I'm looking forward to that.
Ant-Man and the Wasp was a worthy sequel to the first, bringing more good action and great humour. Finally seeing Hope (Evangeline Lily) bust out as the Wasp was great, and Michelle Pfeifer was great as her mom--the ending made me all warm and fuzzy, even as the after-credit scene made me vaguely sick to my stomach.
Infinity War as good enough but I feel like I can't really form an opinion till I see Endgame.
Spider-kid Homecoming was fun, Tom Holland is a good lead, but I can't really endorse anything Spider-man that doesn't also include the symbiote/Venom.
Black Panther was better than expected, it would probably be my 4th choice for phase 3.
Captain Marvel just wasn't enjoyable enough, even though I love the character and want more of her.
Benedict Cummerbund was really good as Dr Strange but origin movies kind of annoy me, even if this character definitely needed one.
