I love Agora so much, for all the reasons you state (it was so marvellous to see a film about a woman who is shown loving her work, for one thing) - the scene where she and her father's slave/co-researcher discover the mathematical model to account for planetary orbits was wonderful, I though, both for their genuine joy and the tiny, tiny moment that joy allows them to overcome their social statuses, and for the confused embarrassment with which their social statuses reassert themselves (and of course, for him, as the powerless one, to be effected first).
