Seasons 1-3 and the 2nd half of season 4 are the best this show has to offer. But the rest is easily forgetful I do not remember a single scene that moved me or stuck with me. Ragnar was what made this show great. Vikings is brutal and has some very dark and complex moments. First 3 seasons 10/10 season 4 7/10. Spinoff would have been better for the sons. Ragnar deserved better and Michael Hirst didn't execute.
