Is it daft to compare this with the Star Wars films?
Well, follow me on this. The underlying politics in Star Wars is all about the Republic being ripped apart by the malice and evil of Senator Palpatine - the Sith Master.
These stories are all about the Roman Republic being torn apart by a number of actions by a number of different men - Marius, Sulla, Pompey and Caesar. And in fact over four books they tell a finer action and poltical story than the six Star Wars films ever could - I'm not knocking Star Wars, just pointing out that 'real' life is sometimes more staggering than fiction ever can be.
Yes, the books are fiction, but based on facts. Okay, it will never be a totally accurate representation of Caesar's life but for a rip roaring read this is beyond doubt a great quartet.
