Short review - it's obvious there wasn't the same sort of budget for this spin-off, and it does show a little in the production value - the dragons and scenery look like they were done on the cheap, but they're still passable.

The cast is reasonable, but they seem hamstrung by a slightly poor script.. they come across a little bit like people pretending to be their favourite characters on GoT. There's none of the clever conversation that we were used to.

I was going to complain about the lack of grittiness, but then remembered this is a period when all was good in the Seven Kingdoms (initially), so it's understandable that things would actually be quite nice and not so caked in mud!

So not much more to say beyond that really - it'll be better to judge properly after all ten episodes have aired. If anyone is saying this is the best/worst thing ever, ignore them - it's impossible to know until we've had the first season, so approach with an open mind.
