I have mixed reactions to this.
The good: it looks like Arrow is going to use his lethal weapon to kill people, rather than strap a boxing glove to the tip of his arrow or whatever idiot thing he does in the comics. This also has a more serious feel than Smallville. Sweet training montage.
The bad: hello, melodramatic voiceover. There are simpler ways to say “I’mma kill me some bad guys.” You do not need to hand-forge your own arrows. And speaking of arrows … I still have a really hard time accepting that Bow and Arrow Man can take out Machine Gun Guy, Bazooka Joe, and Pistol Girl. I don’t care how many tennis balls you murder in your Arrow Hovel.
