It's a bit harsh to say there are absolutely zero positive messages. The lingerie is mentioned, and it is a bit more revealing than I would like for the teenage boy audience, however I decided it wasn't sufficient to edit out nor to prevent my 13 yr old from watching. Not too revealing, but for some might be worth editing out. She stands up and wears the sheet as a night gown. Scene with female lead laying in bed with only a sheet over her. Not mentioned in the Sexual Content in the CSM review:

all of the female roles, by the way, are shown as weak merely workers performing a task they have to perform, for some reason, although it's never clear why - at least catwoman in the last film took control of her own destiny, for better or worse). In my opinion, this movie objectifies women unnecessarily, and it's rather typical of the 90's movie approach, which is unfortunate, but hopefully creates an opportunity to discuss the obvious flaws in the presentation of the women in this film (um. I'm very cautious about young teens viewing sexual content, I believe it leads to many undesirable outcomes in life. I was disappointed that there weren't more jokes about 'holy metal island, Batman!' Or similar. Jim Carey earns his repuation as an outstanding riddler. Overall best movie of the first trilogy, well-produced and fun.
