ONLINE POKER - SITE - PokerRoom

graphics are great, site is nice -- I'm not a big "site is rigged" person but the beats I've seen have been crazy. AA vs KK - flopped K, one outers caught, full house beat by quads, AA VS 3-6 336 on flop, and that was just within the last two days. Is it rigged or is it just bad players making bad calls and catching? I don't know. I'm considering switching sites if I see much more of the crazy outdraws.
