6.0? Really?
If you watched this movie expecting an edge-of-your-seat thriller, yeah, I can see why this movie would disappoint. For that reason, it's a shame that it's categorized as a "thriller".
However Blood is a kind of thriller, an emotional thriller. It's a very poignant and powerful, almost Shakespearean, drama with first-rate performances, great direction and beautiful cinematography. So, I'm not sure why the movie's rating isn't higher.
