Cliffs:
Phase 1 MCU especially Whedon MCU had more significant character development and better visuals compared to Russo bros MCU. MCU problems are most apparent in the Russo bros directed films.
MCU phase 2 and 3 = not enough color...too drab and gritty.
Thor 1 has more impressive visuals than IW despite being 8 years older....
Avengers battle of NY action > anything after it
Aquaman visuals are a great example for the MCU to follow
MCU Phase 3 doesn't show the heroes caring for and interacting with normal ppl like Whedon's movies did, or doesn't seem to care about civilian deaths.
"In the first Avengers film, it feels like New York is really in danger. In Infinity War, it feels like only the super heroes are in danger"
Ragnorak is one of the best of phase 3, but still lacking in color.
Every 3rd act of MCU phase 3 is the same - big battle.
In a nutshell: "I love colors. Phase 2 and 3 have fewer colors, therefore phase 1 is the best phase".
