Weird Father/Daughter relationship

Did anyone else get the idea that there was maybe something more going on between daughter Norma and papa Lionel? Norma Shearer's character is constantly calling her father, Lionel Barrymore, "darling" and "dear" and "sweetheart." She's also extremely affectionate with him, rubbing and petting him all the time, like when they were camping and he had his head in her lap and she is rubbing his hair VERY lovingly and calling him "darling." He doesn't appear to reciprocate, however, maybe because he's totally loaded throughout the film. Also, what was the deal in the opening scene where she was in the bathroom naked and called her drunk daddy to bring her "a complete outfit" and he walks in the bathroom bring only various forms of slinky panties and bras? Not that there's anything wrong with this, but as much as I loved my dad, we were never quite THIS affectionate! She wasn't even this romantic with her lover, Gable. I mean, I know this was "pre-code" and all (which I love and I guess was the reason all this was allowed, especially the fact that her character is opening having pre-marrital sex with Gable, on HER terms, without wanting to get married) but jeesh! And she won an Oscar for this?? I guess with her being a silent screen actress for so long, she was still used to acting with the Big jestures and ridiculously over done facial expressions. Loved Gable, though. Poor Leslie, her scorned fiancee was, as usual, an effeminate pansy. No wonder she choose Clark!
