As a fan of Luc Besson, my expectations were pretty high. He's got a particular style, despite majority of his most popular films being sci fi or action, there's a certain quirkiness to them, some darkness too. Valerian had great special effects, average acting and a pretty good plot that didn't have plot holes, actually made sense and was kind of applicable to real life actually. Personally not my favourite sci fi movie, nor my favourite Luc Besson movie but still a good watch.
