So, I watched Valerian and the House of a Thousand Corpses.
It's....complicated. My feelings about it, not the movie itself. Ok, the leads aren't likable (and I like Cara Delevingne) at all and their dialog is some of the worst I've ever heard in a movie, like actual worst. Getting into The Room territory. Cara is British, why make her do an American accent? The cast is British, French, German, etc and they all get to talk with their own accents. Why make a supermodel who's acting skills are suspect to begin with talk in an accent that isn't their own? On the other hand, it's gorgeous and fun to watch and you're constantly being visually stimulated in a good way with all the inventive and fun stuff onscreen. There's tons of Luc Bessonish madness going on, like Ethan Hawk playing a spectacularly weird looking space pimp.
The best way I could describe the writing is it's something written by someone who isn't a native English speaker and I don't know Besson's directing style, but I feel like he doesn't allow actors to change dialog to something more natural sounding, because no one sounded natural, or even human. All the dialog was cringe worthily bad. Oh, and I think Besson has issues with women drivers, because they make jokes at women drivers' expense like a half dozen times.
It's bombing and I'm not surprised. It's like the perfect example of a flawed but watchable movie. Like John Carter of Mars territory. It's not good, but it's not terrible either.
