The battle itself was great, I watched it on my phone during breaks at work and had to go back and watch it on my big tv, even the scenes with all the brothers together are great, it's just when they're separated and all playing the part of 1/4 of Ragnar (which I guess is kind of the point but it still doesn't work as a viewer).
The Floki storyline is the bit that's really annoying me for going absolutely nowhere, can we fast forward to the bit where Edge dies taking a sword meant for Floki from the guy from Lost girl and spare the wasted time, we finally struck gold on the other plots.
