Simply put, spoiler free:

Rating: 10/10 (6 February 2020)

This is a real review. The 10 isn't me being funny; this is my system: any movie can be a 10 if it is GREATER THAN THE SUM OF ITS PARTS, however I see/ deem fit per each individual movie, in no comparison to other movies, except to help make a better judgment in terms of relativity and consistency in my rating system.
That being said, it gets a 10, because:
1) great casting, big and small, right choices were made, though not necessarily irreplaceable.
2) great performances by cast, with Leo leading the show like the master he is, though not particularly the best performance of his life he's just great all the time he chooses to work. Great support no doubt, each actor has continued on careers of their own lead roles.
3) high budget means it didn't need to cut corners to make the movie happen, so like all the crazy gravity defying scenes, environments, action scenes, top quality script, top notch cast only money can buy.
4) cinematography, top, shots look great, masterful, specially the water shots just stick to me like they're my own life memories.
5) script/ plot, innovative and clean to the point. Lengthy movie that is pretty much a thrilling ride the whole time. Though it concerns the whole entering dreams Sci fi aspect, it feels like a thriller in general, so even though it satisfies the science fiction genre, it does not count out audiences that are not fans of science fiction, like my mother for example, though the dream stuff does go over her head. Story/ movie could have gone many different ways, but overall good decisions were made for progressing and concluding the plot.
6) open ended resolution but that can be debated, in terms of getting closure for our protagonist and what his future holds.
7) it's a movie worth rewatching which I think is probably the most fundamental and consistent trait of a perfect movie, which leads to the next point.
8) timeless, I do believe this movie will stand the test of time because of its unique plot and quality and minimalist of any cgi used.
Finally, this could definitely be a 9, or an 8, or maybe even a 7 to some people... but realistically i don't think anyone on earth would or should give this movie less than that, because work and passion went into this movie; there is no way around that, and I happen to be one of the critics who appreciated all of it.
