I could say I was disappointed, except I wasn't expecting much from it anyway.
Kind of lost interest by about halfway through and found myself being more amused by people's comments about it on Twitter.
It seems to borrow a lot of elements from Merlin, so it feels quite similar in tone, but it doesn't have the great actors that Merlin did. I mean, Mark Addy's ok, but I never would've pictured him as Hercules and I still can't.
I will watch a few more episodes if I'm at home when they're on, but it's not the kind of thing I'd seek out on the iPlayer. Unfortunately, they've missed the chance to introduce things at a reasonable pace and make the main character relatable by having him ask common sense questions such as "how am I understanding ancient Greek?" and "No, really... how DID I get here?"
