The only way to know is to watch of course, but it's been picked up by another On Demand service here than Netflix, so I doubt if it comes to Netflix here ever like in some other countries.
The blu-ray set is out here, but it's a bit of a gamble to buy it if you're not sure about it.
One thing I liked about Twin Peaks the original series was the humor. I wonder where that came from, because on the whole Lynch' films aren't that humorous; they're weird and dark, and sometimes the weirdness can come off a bit humorous, but in his other films he's never broadly humorous as Twin Peaks often was (the scenes with Lucy and Andy for example, or Ben and Jerry Horne).
And when you look at Mark Frost's other work (he's mainly known for Hill Street Blues) it isn't particularly humorous also. So I wonder how the humor became such a big part of Twin Peaks.
