The Ending (spoiler)
I've just watched this movie for the first time, and I have to say the ending disappoints me. Perhaps it is the casting of the lead but Crichton seems far more suited to the lady than to the maid, both because he seems to be of the same 'class' as her in most repects and also because they clearly have genuine chemistry together wheras he and the maid dont in my opinion.
I know it's only a comedy but I think the ending would have been more believable if Crichton had been a polished but working class man who ultimately felt drawn to be with the girl from the ranks who he can relate to, rather than which he comes across as a genuinely posh employee who may be down on his luck but who could easily adapt to marrying a lady. But again this may be down to the casting.
