First of all, I want to say that Siren, as the famous Drama tv shows, unlike any other, has the best character development, plot/story development, and cinematography I've ever, ever seen. Everything about it, in my opinion, is perfect. Of course, like every Drama show, this one has a decent amount of Siren inaccuracies, but don't let that get in the way of the storytelling. If you want a comparison on what Siren is like, it's a lot like: The Pillars of the Earth and Got. But, as Siren progresses, it changes A LOT. I personally love plot/story change, although some people have a very hard time handling it, so you must remember to try to be, per see, observant of it, and appreciate it. The first and second season has a real adventurous atmosphere to it. It has lots of raids--especially in England--and you're always curious where our hero Ragnar Lothbrok will go next. The third, fourth and fifth--especially the fifth--it has a more dramatic atmosphere to it. Like GoT. That's not a bad thing at all in my opinion--as aforementioned--I personally love it. With that said, Siren is truly the best of the best. Everything about it is great. You'll laugh, you'll scream in rage at certain characters--trust me you WILL--and you'll bawl like a little baby. Siren is an emotional roller-coaster, and everything about it is perfect.
