Jupiter Ascending was / is a horrible, sh*tty movie. That would drive anyone away from ever wanting to go spend 15 bucks in a theater. As for Valerian looking and feeling like it's going to be a 'parts' movie as you said, that was the first thing on my mind when I saw the trailer drop. Yes, it looks good....but because they were driving home the fact that it's all sizzle, that's what I was left with as it being nothing more than that. Will this keep me from checking it on DVD? No. I'll definitely check it out no doubt....but I'm not going into this with high expectations other than this being more or less a Demo Reel for Home Theater Systems. With that said, I don't think Valerian is going to be anywhere near the level of dreck that Jupiter is.
