The series has been great so far but this episode was poorly written and goes head to head with the realism and magnificent history up to this point. Four of the main characters (Ragner, Rollo, Bjorn and Floki) was either unmistakably dead or about to die, and all of a sudden, all of them are back at their camp. I know that main characters rarely dies, but in this instance I would say that not letting somebody important die is a massive mistake. It truly destroyed a very interesting and otherwise great episode.
