Misguided political correctness
I realize that everybody is entitled to their opinion, but one of the more recent user comments really got my goat with its "political corectness". I will go so far as to agree with them on the acting. I have seen the final scene on YouTube, and yes, the film is horribly acted by all, even the great H.B. Warner, who clearly had not yet adjusted to the film medium.
However, I must take issue with all who believe that the film endorses wife-slapping or beating. Neither the film nor the play nor the musical based on the play do so. Julie forgives Billy for his behavior because she understood that his actual motivation was his frustration at not being able to provide for her without either (1) agreeing to Mrs Muskat's request that he abandon her or (2) committing a robbery. She did NOT forgive him because she got off on being beaten or because she thought it wasn't so bad. And the heaven sequence (both in "Liliom" and "Carousel") takes pains to point out that Liliom's abusive behavior is wrong.
