The spoiler-free review I gave to a friend immediately after seeing it: More fun than Rogue One, but maybe less "impactful" to the SW canon, overall. (In terms of it doesn't really add a lot of weight or critical backstory to the established canon, aside from one or two key moments.)
Solo: some neat nostalgia, Lando was extremely well played and the movie could stand on it's own amid the universe. However, I didn't find it...fun. Worth seeing, but not high on my list of favorite SW movies.
I quite enjoyed it!!! I always try (really hard) not to compare any of them or declare a favorite; as I enjoy each for what it is, but I didn't find myself poking holes in it or wanting to edit out scenes and characters as much as The Last Jedi.
...besides who doesn't love Millennium Falcon porn...?
