Spoiler alert! The following contains details from the series finale of "Stranger Things": "The Rightside Up."

After nine years, five seasons and a whole lot of Dungeons & Dragons terminology brought into the popular lexicon, "Stranger Things" is finally over. Was it worth it?

Maybe? Despite the Godzilla-like monsters, flame throwers, a real death, a maybe fake death and more heart-to-hearts than a middle school sleepover, the two-hour-long series finale ends with more of a whimper than a bang. It's an episode full of logical fallacies, unearned emotions, frustrating plot holes and twists meant to be scary that end up being straight-up silly.

Creators Matt and Ross Duffer threw everything and the kitchen sink at this movie-length finale (that is running in actual movie theaters), and it was all too much, and not enough.

The problem is that "Stranger" possibly can't end with any sort of satisfaction. It's become far bigger than its humble origins. At one point, this was a small sci-fi show that paid homage to 1980s movies like "ET." Now it's a money-making machine that's more CGI than human, that keeps flashing to a kid wearing an "ET" shirt.
