This realy is like a western.

I'm pretty sure Piirainen is a big Leone fan. There is many connections to his spaghetti westerns. For example: The last line, Raid's harmonic harp, Takamäki's words to Hammar when Hammar is about to kill him, Raid is watching Once Upon A Time In The West and knows it inside out. And there is other themes and elements from Leone's movies too: Friendship between men, revenge, flash backs, and the final duel. And isn't Raid like Harmonica or Eastwood's character from Dollars Trilogy?

This is just my gues but I think Piirainen has seen his opportunity to put all his love to Leone's westerns and realy have done it. I think this series is better than any of Tarantino's movies who is too ispired by Leone. It would be interesting to know what he would think about Raid if he saw it.
