With Lake & Michelle gone, the boring, predictable stereotypes remain, with the exception of the hippies:
Joseph & Monica - boring, predictable caucasian couple
Ray & Yolanda - boring, predictable black couple
Fran & Barry - boring, predictable old couple
Eric & Jeremy - boring, predictable alpha-male types
Only BJ and Tyler have character--if they go, then it will be the most boring, predictable final four ever.
