I tried so hard to like this...
Just finished the entire thing.
I loved The Maltese Falcon. I love the French countryside. I like Clive's acting. Tie all that up in post WW2 France with a murder mystery and I don't see how it could fail. I wanted to like it so much that I ignored the problems.
It's slow. Not a slow burn, but just really slow. They have a lot of characters and subplots that really aren't that necessary. You could have cut enough fat off this thing to take away two whole episodes. Then the finale (see below) could have been stretched out so it didn't feel so darn rushed.
Honestly, two characters show up at the beginning two episodes for a scene each, then you forget about them and they show up at the ending. You have these long scenes with side characters where they talk about stuff that has nothing to do with pushing the story forward, and in the end you'll realize those scenes didn't matter. You feel like they have a movie script and decided to stretch it out to six episodes and the best way to do it is a whole lot of nonsensical filler stuff.
However, that isn't enough to not watch it. You can get by with the gorgeous locales and solid acting. This is why you shouldn't watch it.
The last episode of this might be the worst finale I've ever seen. It was as if they had four more episodes to do, ran out of money, and said, "We need to wrap this up in twenty minutes." There's a very odd shootout and then, no kidding, a new character comes out of the shadows and says, "I'm now in charge because I'm me and we are ending this with a discussion in a chalet where I tell everyone off, then we roll the end credits." You'll be thinking you just spent 5 1/2 hours for it to end like that?
