The Marvel Cinematic Universe (MCU) might be the most popular media franchise in the world, but that doesn't mean it's without flaws. There have been plenty of healthy discussions about what Marvel movies get wrong. Some worry about the tone of the MCU, asking questions like, "Do the Marvel movies have too much comedy?" Others point out specific characters, plot elements, or entire films as trouble spots. In other words, although the MCU is the most loved thing in the universe right now, that doesn't mean it's universally loved.

Thor Does Cosmic Better Than The Guardians Do
From Redditor /u/DraftDraw:
I actually enjoy the cosmic aspect of the Thor trilogy more than that of the Guardians of the Galaxy movies. While the cosmic societies and worlds surrounding the GotG films seem more alive, the Thor movies look completely alien and very artistic - from Asgard, to Jotunheim, to Sakaar - and the alien designs are much more creative, while most aliens and locations in GotG outside of Rocket and Groot look very human-like, with human clothing and human-like cities.
The Hulk Is Actually Underpowered
From Redditor /u/JonSnow31391:
Hulk has gotten the short end of the stick lately. Hulk is supposed to be the strongest Avenger physically. His durability and strength should just edge out Thor. Thor might be more powerful, but recently the movies have shown Thor as stronger as well. Part of it was because Hulk got beaten in Thor: Ragnarok. Of course you can't have Thor lose in his own movie, but they showed Hulk being winded much earlier than Thor. I think they needed to show Thor using his lightning on Hulk a little while longer instead of just one blast.
Additionally, Hulk losing to Thanos should happen. But when the same movie shows the guy who beat Hulk also surviving the force of a full star, and then defeating Infinity Gauntlet-powered Thanos with one blow while charging into a beam from the Gauntlet, it puts Thor waaaaay above Hulk in showings.
'Age Of Ultron' Is A Great Film
From Redditor /u/occupy_westeros:
Age of Ultron is pure, campy greatness. The action scenes are great, everyone is wringing every bit they can from the script, and James Spader as Ultron is amazing. I think it's aged really well, and people are too hard on it because they didn't know where the MCU was going. It's kind of the Attack of the Clones of Marvel movies, and I mean that in the best way possible.
'Thor: The Dark World' Is Not The Worst MCU Film
From Redditor /u/Malfoy87:
I love The Dark World, I've seen it so many times. Every time there's a post here about the worst MCU movie, almost everyone seems to list TDW, and while I agree it's not a perfect movie by any means, it's not that bad. All the scenes in Asgard are great, the Thor/Loki prison break is so fun (with a Cap cameo!), their battle in Svartalfheim was amazing, even the last arc in London was fun to watch. I didn't like the Earth scenes, but all the rest is what makes me want to re-watch every time.
