Is Vikings a good show?

I keep being told about this show, but I don’t have cable, so I can’t watch it. I get all my TV needs from the PlayStation Network, where I can rent episodes for a low price and watch them on my PS3. Unfortunately, while their selection of shows is huge, there is nothing about this Viking show.

Of course, I’m interested in watching it, and I think it’s interesting that they ditch the stereotypical horned helmet Viking in lieux of something that’s a little more accurate to what Vikings were. Reading about it on Wiki, it is apparently filled with historical inaccuracies, but it also goes on to explain that not very much is actually known about the period this happens in, and that a lot of the recordings that do exist are biased. But whatever, I think it’s a cool idea to make a TV show about Vikings based on real dudes and actual events. If I can have fun and learn something at the same time, seems it would be a cool show.

…but I have no way of watching it, currently. So, have you seen it? Is it any good? Does it suck? Thoughts?
