The Dracula BBC miniseries from a few years back has three episodes, and one of them is entirely devoted to what happens on the Demeter. It's a fun variation on the story, basically positing the whole thing as a supernatural whodunit.
Bug is one of those movies that, when it came out, every horror person I knew saw and liked, but then it's sort of fallen off the radar since then.
Everyone go watch Bug as a double-feature with another film that suffered the same fate: End of the Line.
Still, I humbly suggest Friedkin's Bug (2006), a weird little claustrophobic thriller that takes its time but eventually goes completely off the rails. Fair warning, this gets intense and legitimately disturbing once it gets going.
