Avengers Infinity War - When it came out I called it a modern day Empire Strikes Back, upon rewatch that assessment still stands. Easily the best Avengers movie and a top 3 MCU movie for me personally. 7 years later and it still feels like a special movie and the ending still leaves an impression, as much as I like Endgame and think it's a great conclusion, Infinity War is better able to stand on its own. 9.5 out of 10, and the only reason it's not a 10/10 is entirely personal bias, namely the absence of my favorite superhero team, the X-Men(and this holds especially true for its sequel, Endgame)
