If you're shooting nothing but talking with static cameras then 24fps is adequate. There are some great films (eg. 12 Angry Men) that have no major frame rate problems. But this style is not a good demonstration of film, because it would work just as well as a stage play. I mentioned action genre because it's a better demonstration of the potential of film and it suffers tremendously because of the low frame rate.
