Would rate 9+, if this is a standalone movie

Rating: 8/10 (4 May 2018)

It would be the darkest superhero movie if everything just stop here. Supervillains eventually won this one, and retired peacefully. Heroes are suffering from losing their comrades. Fans are hung there FOREVER. Those good actors could finally go back and focus on real acting performance.
How ridiculous it sounds? No way MCU will quit exploiting this trillion dollar IP which they have spent more than a decade to build. Actually, the after-credit scene has already revealed that Cpt Marvel is coming. Ant-man and the Wasp are only two month away. Dr Strange promises that as long as these fellow up movies could make more than 14 million dollars, fans would see they win. Easy peasy. Fans, just go see incoming MCU movies, make sure the company won't break before part 2 comes out. It is not that hard to bring the other half of heroes back from another universe where "Zayn is still in One Direction", as mentioned by Stephen Hawking. If Rick and Morty can do that, Tony Stark can definitely do the same.
Sorry for being off the point. The whole movie is fabulous. It has the greatest visual effects and the most prestige cast you could expect. There is a fight scene after another. If it were a standalone movie, it had the deepest and the darkest story comparing with other MCU movies I had watched. I actually haven't watched too many of them. Logan is rather sad than dark to me. Some plots don't make sense to me. Some of them are because I haven't watch all other MCU movies. The others are called eastern eggs for future movies.
