When reading a commentary on Aristotle, you need to be aware that there is an issue the commentator is discussing about Aristotle. Not all will agree on the issue. There may be other ways of reading Aristotle that are better and more convincingly defended (in arguments). Responsible commentators will alert you to views contrary to their own, even when those views are not central to their arguments. Commentators on Aristotle's work try to explain, clarify, justify, criticize, support and undermine Aristotle's arguments. To do so, unless they are trying to update Aristotle's thought, they must consider Aristotle's views in the context of Ancient Greek thought. Thus, you need to be clear on the commentator's purpose, and how contentious their view is. What was once an obscure reading of Aristotle may now be standard, and what was once a standard take on Aristotle may now be considered mistaken.
