This is a sci-fi novella on three disks (I think it's about ninety pages long). I found I wasn't as impressed with it as I thought I would be when I read the blurb!
There's supposed to be this galactic TV show, and the aliens' idea of entertainment is to watch this one celebrity named Pom Trager messing with things on our side of the universe. The guy claims he's tinkered with every president since Nixon, bringing hassles into their life, although why he's so obsessed with US presidents goes unexplained other than that the author is American, which is pretty pathetic and thoroughly uninventive. Why the universe is so interested in Earth is another unexplained mystery (other than that the author is from Earth). I find these conceits to be provincial and annoying.
This idea in particular is problematic, because it's like the author wants to criticize the US but doesn't have the guts to do it directly, so he puts the observations into the mouths of aliens, like he knows what aliens are thinking, but it turns out that the aliens' minds work exactly like human minds, so it's not only unimaginative, it's also boring and it makes the aliens look like morons. It's really no different than what Star Trek did with Commander Spock in the original series, Commander Data in the Next Generation, Neelix (whom I couldn't stand) in Voyager, and full circle back to the resident Vulcan, in the form of Commander T'Pol in Enterprise. Yawn. And Yuk. Star Trek Discovery will no doubt be exactly the same.
In this take on it, Trager falls through the divider between his world and ours, and ends up in the Rio Grande about a half hour out of Santa Fe. There's a reason things go wrong and it's so trite as to be worthy of a high-school story writer. Trager has to make it to San Francisco to catch a portal back to his own world otherwise he'll be trapped here in our world and that's your story. The handling of it was amateur and painful, and in the final analysis, it's not even remotely about aliens, it's about us - again. It just felt like a poor idea for a story. The length of it is just right for a movie, and given Polster's professional history, this is probably what was intended. So it failed as a screenplay, and now the author is trying to unload it on us as a novella? No thanks!
