How historically accurate is 'I, Claudius'?

by Kayters

Hi guys,

I'm tempted to start watching I, Claudius tomorrow. I've a flight to catch in the morning and I need something interesting to do.

Out of curiosity: how historically accurate is the series? I know it's well written and everything (from a narrative point of view), but... what about historically accuracy?

Are there any other TV shows worth looking at that depict the same historical period in an accurate way?

Thank you!
