Personally I think most of Aniston's films range from average to pretty terrible, with more films fitting in the latter category. However, this is just my own impression of her work. I have no data to back this up. What's more, in order to make an assertion about the quality of her work I would need a baseline to compare it to (e.g., average quality of all movies released, average quality of films released by former Friends cast members) and depending on the yardstick, Aniston could come out better or worse, so it's not really a question worth asking.
On the other hand, I can evaluate the quality of her body of work over time using data from critic and fan sites to determine if there are any interesting patterns in the data (e.g., trends in quality and box office revenue). That is what I aim to do with this post.
