The movie was complete bullsh!t. There are many plot holes, a poorly written script, inaccurate historical representation and a f0ckt up timeline.
EX:
1) Came back from the crusade with his house burnt down etc but yet nobody question where he gets the money.
2) How long did it take him to train?
3) His "mentor" has done setting fire in a public area, but nobody notices are remember his face (not even the guards).
4) How is he healing so fast?
5) Is he a time traveler because his fashion looks very modern?
