I've just watched Valerian and the City of a Thousand Planets, http://www.imdb.com/title/tt2239822
. It's the most expensive movie ever made in France (figures vary, but 177 million US dollar is often mentioned). From its box office results, perhaps the last French attempt on a big budget movie for a long while.
That's a shame, because it's really well made, with lots of details and energy put on bringing the world to life. If you want a sci-fi spectacle, best viewed on a big screen, then go see it. If you want entertaining action, characters and humor, then go see it.
While the story is far from as dazzling as the visuals, it's not as clear cut or generic as most and I found it interesting. Then again, I have a tendency of liking big budget disasters, like Jupiter Ascending or John Carter.
I'm just back from seeing it. I liked it, though it definately has it's share of problems. The visuals are great, but the story is very predictable and the characters, both good guyus and bad, are rather boring. There's zero chemistry between the main characters, and I didn't really buy their romance for a second. Also, the movie feels very unfocused, as if there's almost too many ideas, the whole, let's call it, "Rihanna episode" is entirely unrelated to the plot, could be cut without missing anything, despite taking a big chunk of the movie. It's a fun episode, but still.
But there's plenty of fun concepts, great designs, and the interdimensional bazaar heist part near the beginning was really clever and fresh. I actually regret it's set at teh movies beginning, it would have made for a more interesting climax than the rather by the numbers gunfigh/race to disarm a bomb.
Anyway, despite teh problems, it's fun and worth seeing on the big screen. Just don't expect it to measure up to the Fifth Element.
