As close to a 10 as I've seen

Rating: 10/10 (27 April 2018)

I knew from past Marvel movies and the trailers that this would be a good movie, but it exceeded my expectations in every way.
One big problem with the excellent MCU is their weak villains and the lack of consequences for the good guys.
This movie brought us excellent and very strong villains, as well as plenty of consequences for the good guys.
There was lots of well-placed humor. Unlike the new Star Wars movies which can't place a good joke to save their lives, the MCU really gets that aspect of these movies.
I was wondering how they could make this movie without considerable violence...not our usual fights, but true violence. They didn't pull any punches. This movie is the most violent of the MCU by far. They didn't sugar coat this movie for the kiddies.
Thanos is amazing. Not just a mindless bad guy, but someone with a fleshed out character and clear motivation. Whether you agree with his reasoning or not, you can still relate to him because our own history has seen similar ideas from the Communists and Nazis. "Genocide for the greater good" as monsters from our past have declared it.
If you are a fan of the MCU, this movie has everything you love from the previous films and everything you have wanted but haven't seen.
I give this a 10/10 after two viewings (now five two weeks later). I find very few flaws.
Edit: A couple weeks later and I have to laugh at all the recent 1/10 reviews. The DC fangirls are waging a unified rating war from their Mom's basement in an attempt to drag the rating down to that of movies like Justice League. All the while, Infinity War races to 2 BILLION dollars and is already #5 top grossing of all time. Keep hoping for a good movie, DC fans. Nothing will touch this, though. Over half of the people who have seen this rate it 10/10 while 1/10 is less than 2%.
