The worst thing about this film is the acting from anyone not named Claude Rains. The most annoying by far was Una O'Connor as a co-owner of this bar Jack lives above at the start of the film. You know that scene in Clue where Mrs. Peacock thinks she's been poisons and gives a shrill, annoying scream until she's slapped? Imagine that shrill, over-the-top scream for 25 straight minutes rather than 10 seconds. If I didn't have to watch this film for this project, I would have turned it off in that first 25 minutes for that alone. It was the most unbearable, annoying character I think I've ever seen.
That being said, it does start to get better after that. Most of that is actually thanks to Claude Rains, whose mostly vocal performance is pretty fun. Also, the visuals of the film are interesting--some fascinating--due to the time period it was made. Any of the invisibility tricks (including the ending shot) are in particular great.
On the whole, though, the film is just kinda dull. There's some interesting aspects, but when you don't give a damn about any of the characters, it's hard to care about the story. No character is three dimensional (...no pun intended?). And you don't get to know Jack before he becomes invisible, so he's already crazy by the time he's introduced. Because of that, you don't care about him, his transition or journey as a character, his relationships with other people, or really anything about him. And the people he associates with are pretty one-note, as I mentioned before. It's just either cops that are coming after him, a guy who won't work with him, or the woman he once loved who still loves him. (Fun fact: this character is played by Gloria Stuart, who you might know as Old Rose in Titanic. Funnily enough, her character's name here is Flora... as in plants and flowers. And she's in love with a guy named Jack. After almost 70 years in film, she really didn't expand her range much, huh?) Anyway, if you're into those classic "monster movie" types, it's fine. I just wished it had a lot more to it.
