I thought it was pretty boring for a Star Wars movie. If I'm honest, the movies action scenes were dull and not as exciting as far as action movies go. The plot points of Qi'Ra's (Emilia Clarke's) story and why she was so beholden to the organisation she worked for needed more explanation.

(SPOILER)I had to literally explain to my friend who I saw it with the whole "Darth Maul is alive" aspect of the plot as someone who had only watched the movies and not immersed themselves in the universe fully would have had no clue that Darth Maul was alive.

If you're watching just the movies it makes the timeline make no sense. As it makes the events in Solo seem prior to the events of Episode 1 which means the presence of the Imperial forces very strange as they would be in existence some 20 years too soon.
