Felt like the same old... Extremely similar to, though not as good as, Marco Polo, The Aztecs and The Reign of Terror, thus it was rather repetitive. It didn't really have a unique quality to it; it's just another story where they go back in time, one of them get kidnapped, they save them, they have to do such and such to get back to the TARDIS and escape, etc. It was rather uninteresting, unfortunately.
However, the costumes were done nicely and it was pretty cool to see Ian get knighted. And at least it wasn't as bad as The Web Planet. :POther than that, it was pretty meh... It wasn't bad and it wasn't exceptionally good. It was just... Meh. I just think it's that these historical stories give the TARDIS crew nothing to do or solve other than to live through it and escape. There's no sense of adventure here - for me personally, anywho.
2 stars.
