Yes, the walking around in space was distracting for me but at least there was a scene where a droid needed a helmet when in space. They acknowledged what they were doing.
I watched the English version and Alison Brie (an actor I usually very much enjoy) dialed it up to 11 with most of her lines. She seemed like a parody of a villain. The brother (Neil Patrick Harris) was fine but his motivation was sketchy at best.
The designs here were appealing and in most cases very fitting for Star Wars. Too bad the story and execution didn't match.
