If you read post #42 in this discussion, you'll see what I think of UFO's. Largely my opinion is similar to yours (
wtimothyholman) on the whole.
I'll also add that the whole topic of UFO's (or whatever anyone wants to label it these days) is and has traditionally been inundated with, for lack of a better description, nuts, idiots, and morons, most looking for some kind of angle to make a buck. Not everyone, but it certainly has attracted an "eclectic" interest. Even the so-called authorities on the topic appear to be unusual in nature and appearance.
That stated, I watched the aforementioned documentary on Travis Walton expecting to enjoy a good laugh. I ended up being mystified as to how a group of what appeared to me as "regular, ordinary working guys", (like any of us maybe) could not only fabricate such a tale, but then keep their accounts straight between themselves. When they reported Travis missing, they were all under suspicion of murder - it was presumed by police that they'd killed him and hid his body somewhere out in the forest they were working in. (Never mind that the foreman was Travis' best friend). They grilled each of them one at a time and used polygraphs which they all passed. These are regular working guys - yes you can fool a polygraph - we all know that, but it isn't that easy to do without training.
