War scene kinda creative. Just replace the modern weapons with arrows, bows and crossbows. Pretty good action I'd say.
Story wise, you get to see how Robin came to be what he is from a Lord to being a "Thief" and how John became his "buddy-master", the adviser, plotter and trainer.
Overall, it's refreshing and I think you have to watch it with an open mind or you may thread on a thin line to be cynical and critic over what you knew about the good ol' Robin Hood we all knew. If you compare to many Robin Hood movies made in the past, this is actually watchable.
Give it a watch ya! Have fun!
