AKo - did I play this badly?

[LordBaldrick]

I played this hand on PP about an hour ago. The Villain was running at 50/0/2.5 after only about 30 hands so I had little opponent specific knowledge to go on. Given that I played my hand passively Preflop - should I have aborted this hand earlier or for that matter, should I have called on the River? cheers.
