I did miss all the rest of the characters, also. it did explain a lot about Wolverine, but the connection to Sabretooth was good except for 1 major flaw. In the past movies..they made Sabretooth seem like a mindless beast with not thought or feeling, just animal instincts. Although, in the Wolverine movie he has thoughts and actually a "smooth killer" character, that actually had speech. So, are we to believe he mutated more and lost all his "cool" characteristics? Just my thought. But...great movie all in all.
