Julia Misbehaves (1948)...does she?

Last night I saw my third film starring Greer Garson. I liked the previous two, "Mrs. Miniver" and "Random Harvest", but I wouldn't say I'm gonna re-watch this one in the near future (unless someone pays me for that...which is not very probable).

My problem with the movie starts right here, in the second paragraph: the story. Subplots aside, Greer Garson plays a vodevil dancer who was married once to a Rich Guy (Walter Pidgeon) and had a daughter with him. One day (we don't see this but it's remembered during the film) the Rich Guy decides that he doesn't love her anymore (really). So, what does poor Greer do? She sacrifices herself, letting her daughter with the Rich Guy and his mother, because that way she would have a good life.

Told that way it's like "Stella Dallas". But wait, the movie starts when Greer Garson receives an invitation to assist to her daughter's wedding. She accepts. The only problem is that Rich Guy didn't send the invitation, nor his mom. So they try to stop Greer coming down their rich house. Greer manages to see her daughter who is obviously all grown up and all Elizabeth Taylor (there are even some lines about her "violet eyes"). That scene was one of the few memorable things from this movie, very emotive:

Now, the icing of the cake. Rich Guy decides that having poor Greer away from Elizabeth Taylor for seventeen years is not a rotten thing to do, so he suddenly realizes that he really loves Greer and starts to chase her. C'MON!! So, does really Julia Misbehaves?? NO, she doesn't, she has no pride, she has not even a little tiny little desire of revenge.
With a more believable plot Greer Garson would have shined even more. She was very funny and  histrionic: watching her I remembered Barbara Stanwycks' Sugarpuss O'Shea from "Ball of Fire" (only classier). The scenes with Cesar Romero —her acrobatic ultra strong fiancé— are super fun and he is very good in his role.

See? Without that terrible main story, this movie could be hilarious.
