Ugh, the Roman period. I'm kinda garbage on it. But from what I understand, wasn't he mostly just a sophistic guy who tried to effectively do the same thing that Polybios and Ploutarchos did, namely, acclimatize Greeks to Roman rule? You know, where "Greeks" meant "wealthy Greeks who cared about history and could be assed to read his books", who were the only Greeks worth courting anyway.
