Her mother was killed so that monstrosity known as Cassie could be born. Now we're being asked to swallow this time travel nonsense. Looking at it objectively, I can see why Reva and her travails have turned so many people off. This wouldn't be a problem if the writers were creative enough to give her some classic soap opera plots to deal with. As long as they're determined to make her into a Super Diva, Reva is going to have many detractors.
CC is far better an actress, a lot more exciting to watch.
They try too hard with KZ, i'd say give it up. I'm glad i've seen a sample of her next storyline on Fri. CC certainly is a good actress. KZ is just my favorite of the two. In fact IMHO she is the worst actor on the show.
