What is the author's tone in The Twelve Caesars by Suetonius?

Suetonius gathers information from sources and stories he has heard throughout his life. Some of the facts even come from his father who served in the army under one of the emperors. He grabs the reader's attention with his smooth writing. He does tend to switch from topic to topic rather abruptly. He is very subjective throughout the book and does not show any real favoritism towards any of the emperors, pointing out both their good and bad attributes equally, where possible.
