I had no idea Emilia Clarke was in the movie, and hell I didn't even recognize it was her throughout the entire sequence set on Corellia. Too little exposure to her acting outside of GoT/in her natural hair color I guess. So obviously I'm no Khaleesi Fanboi, but I still thought she was one of the stronger elements of the movie. I too was pretty sure her character had to die before the conclusion of the movie (or else why would Han Solo still be Solo later on?). Despite knowing she was disposable, I think I had more emotional investment in following her story than any of the others'. To the writers' credit: while it was totally predictable Han and Qi'ra wouldn't be involved anymore by the end of the film, they didn't go with either of the obvious routes: being killed by a baddie to tease/enrage/motivate Han or being killed by a soul-torn Han because of some betrayal. Her staying loyal to the cartel wasn't totally surprising, but staying loyal AND not betraying Han was a pleasantly surprising twist. I was entertained by that storyline both from the actors' performance as well as the writers'.
The twist that the Mad Max style space-gas pirates turned out to be the nascent rebellion was a fun reveal for me as well. Of course Han wouldn't join the Rebellion as he starts ANH as a Hutt affiliated smuggler... but it was nice to not spend the whole movie pretending to wonder "will he or won't he" join them. (Was more fun spending the movie wondering how Han and Qi'ra would be broken up for good.. and as I opined they didn't disappoint)
During the opening "scrawl" we learned that Han was working for some "Lady Proxima". I was hoping that we'd find out she was something other than some sexy Black Widow type. I wasn't disappointed :D Plus it felt like a meta callout acknowledging Han's future involvement with the Hutts. He's worked for horrible *things* before, why not a giant slug!
Say what you will about the "A Star Wars Movie" spinoff brand, but they're giving us way better Droid characters than the Skywalker saga movies are. Was also a very neat touch to see why the Falcon is actually such a unique/special ship thanks to L-3's "transcendence". And it gives a very fun extra facet to Lando's attachment to the Falcon. It's very fun to imagine L-3 being not so delusional about Lando's affection for "her".
Another interesting thing I got from Solo is that it's educated me really on what the "A Star Wars Story" brand apparently is: generic movies set within the Star Wars universe. Rogue One was a gritty war movie. That happened to be set in Star Wars. Solo is a heist movie. Set within the Star Wars universe. Primary mission isn't to expand the Star Wars canon but simply capitalize upon it. And there's nothing wrong with that. A few callouts to the Skywalker Saga movies are to be expected, but honestly it'd get pretty tiring if every dang movie was meant to provide new perspectives on the Skywalker Saga.
On the flipside, I don't know what the hell happened with that 4 armed pilot character thing. Something about it triggered me, uncanny valley like but clearly not that as it didn't appear to be human-like. If I had to put a finger on it, the voice was a total mismatch for the appearance. At any rate his only redeeming value for the movie was being killed off in short order rather than becoming the next Jar-Jar.
I would have rather seen the whole "12 Parsecs" thing remain the domain of nerds arguing with each other about what it meant. I didn't groan at the relevation of how Han got the "Solo" surname, but a HUGE part of the movie was devoted to that stupid line from ANH and that was a loser for me. Didn't need any of that aspect. So much of the headscratching about the rules regarding the macguffin are there just for this gymnastic effort... "Why does the fuel become unstable after you remove it from this magical room? Why can't you replicate the qualities of that room elsewhere?" is only there because due to this awkwardness in describing why Han measured the Kessel Run in parsecs That One Time. Screw it... call the line in ANH Han testing some backwater rubes to see if they even knew what a Parsec was and it's all an improved story than the canon.
All in all I enjoyed it but didn't love it. My yardstick is "would I pay to go see it AGAIN in a theater?" and in this case, no. I don't regret the money I spent to see it, but certainly wouldn't pay again to see it.
