My notes, before the movie starts: Well, at the worst it's only 1 hour and 18 minutes.
In Pod, there are three siblings: Martin, Ed and Lila. Martin is a vet, struggling with PTSD and living "in the middle of nowhere" which is actually the coast of Maine. Ed is a doctor and Lila is a millennial with a bit of a drinking problem. This is all the characterization you will get for these three. After receiving a disturbing voicemail from Martin, Ed and Lila drive up to make sure their brother is okay. He isn't: he has covered the interior of the tidy little coastal cottage with foil, is paranoid, ranting and raving, has pulled out some of his own teeth and shaved his head, and claims to have been experimented on when he was in the army. Oh, and he says he's got a "pod" locked in the basement, which creature killed his dog and scratched him up something fierce, infecting him. Obviously his brother and sister think he's nuts. But later, after [REDACTED FOR SPOILERS], Ed investigates the cellar - which is a pretty typical Maine cellar, all ledge-y and full of water seepage - and, gosh, he shouldn't have done that.
My notes, during the movie: How many shots in a rifle like that?
As mentioned above, the characters are thin and underdeveloped. I did squirm a little when the tension rose a little: I was expecting jump scares that didn't come, so that made me nervous. There's not much blood/gore and it really isn't scary. The plot is nothing if not unoriginal, but at least what happened made sense in the movie's universe and was interesting.
My notes, at the end: Well, it's not GOOD but it's better than Final Girl.
