I don't think US series are too long. I think they're just badly planned. I prefer the approach you see in anime were a show is usually contained in a single season. If the show does really well they make another show that is effectively the next season. If it does poorly any fans it did get aren't left with an unfinished product. For a planned multi season story arc Babylon 5 is the best example I can think of. The story arc was planned from the beginning and they stuck to the plan. The temptation to keep piling on more content to a successful show is huge. For multi season story arcs I think it's important for Netflix or whoever is making the show to commit to the whole thing regardless of early ratings. I'm far more likely to take a chance on a new show if I know the story line will be completed. I don't want to start watching a show only to find out they cancelled it in the middle of the story.
