So my wife and I have just binged through the first and most of the second season of this. I wouldn't recommend watching it so quickly as some of the flaws become more apparent. My wife likes it, partly due to the costumes and settings. Perhaps partly due to the male lead. Whereas the female lead is plainer (relatively). I somewhat enjoy it but it varies episode to episode. The content and type of story varies so much throughout the series. Sometimes romantic drama, sex and arguments, sometimes battles or raids, sometimes brutality. I suppose that is a good thing in that you don't know what you are going to get.
I watch quite a lot of Horror Movies and as a result have seen some graphic stuff at times. I think though this series is the most graphic, mainstream drama TV series I have seen. Although less so in season 2 than 1. Spartacus now looks modest in comparison. I thought it was a series with a bit of time travelling, a lot of romance and some fighting and politics thrown in. The first six episodes seem to follow that. A bit of intrigue and some developing romance. Then episode 7 is stocked with sex. I haven't read Mills and Boon but that episode is what I imagine for the genre. But then it just keeps on going and gets more extreme. So there is female rape, male rape and then briefly in season 2 even child rape. There is torture and hanging. There seems to be a rule that the main character has her breasts showing for much of season 1. Just another show with the desire to shock.
I don't suppose there is much realism here in terms of the greater story and how life is depicted. Everyone looks so clean. I also don't get why Jamie lives in a relatively small place with apparently few staff in Scotland yet seems to have so much influence. Then his Uncle in France was fabulously wealthy and they can turn up with all manner of fine clothes. Then the way the main characters get connected with royalty is dubious. Then this stuff about the legend of the White Lady (witch) which just conveniently pops up. You can at least say something is always happening. Clair jumps between in shock, to in control of those around her, to being able to act in all sorts of roles. Jamie, some of his close family, and his follower/adopted father seem to be the only "good" people in the show. Clair jumps between wanting to change the future and not changing the future. She calls Jamie's uncle selfish but she sometimes seems to be the most selfish person on the show. Though she always has the healer angle to fall back on
I did enjoy some of the humour. Some of the scenes with the head of the clans etc. Some of the battle scenes. Also the early parts where they have the mythology and religion around the standing stones. There is definitely some good stuff in there.
