Without spoiler please
What do you mean by good? Would you like it? If you like history, bloody battles and power you will like it. If it's just about the series, how the actors are, the quality, etc. It's top.
In any case. A bit long in some places but ok
It depends on what series you like. If you like Game of Thrones, you might also like Vikings.
The series is based on the Nordic legends about the legendary Viking Ragnar Lodbrok and his sons. It is also about historically documented raids and conquests of the Vikings.
One should not expect historical accuracy. As far as I know, the Vikings' clothes and hairstyles are not authentic, for example, and one of the main places of action is the purely fictitious Viking settlement Kattegat, where Ragnar and his family live.
Similar to Game of Thrones, there are intrigues, power struggles and battles in Vikings and sometimes also quite violent scenes of violence (e.g. Someone is brutally executed several times) and occasionally sex scenes.
Also a little bit like in Game of Thrones is that sometimes characters speak audibly in their mother tongue for the audience. This is usually translated either with subtitles or by another person present.
Vikings, like Game of Thrones, is also one of my favorite series, I find it very exciting to follow the experiences of Ragnar and the other main characters. I somehow like that people sometimes speak in their mother tongue.
