First. All game are repetitive. That is the nature of games since cave men found ways to entertain themselves besides sex.
Asgard's Wrath feels that way at the start. You quickly start getting other weapons types, abilities and companions after the tutorial. 
That's just the first character so far for me. I'm told the other 2 warriors you possess in the game also mix things up really well.
The level design is also very good. You never feel like you're in some copy pasted environment.
