As for the film itself, well I'm puzzled. Why was it made part of the Classic Monster Legacy Collection? He's not a monster per-se. There's no reanimating the dead (Frankenstein, Dracula), he's not a long lost living creature (Gill-man), or even a man with a best inside (Wolf Man).. He's simply a scientist who discovered how make himself invisible, and got mad in the process. Nothing monstruous there. Ah well, probably explains why The Invisible Man wasn't in Monster Squad to begin with.
I still haven't seen Bride of Frankenstein. Have you?
Unfortunately he's probably to spoiled now to return to those roots and make another gore classic.
Gore is less but when it's there it's total gross out (that guy eating with a spoon in the opening sequence )
I'm not sure I want to imagine Bad Taste and Braindead made with a budget to look real.. I don't think they'd be as good.
Personally, it's the green stuff Robert regurgitate that they then all eat, including one of the human, who actually ends up liking the stuff!
