I used to like Star the lawyer, but my biggest complaint with Star is and always has been that she's a colossal asskisser. She was the worst with gushing over every single guest that walked through the door. Over the first few years, she was good with the Hot Topics, but like you pointed out, eventually it became a venue for her to name drop and go on about herself. Nauseating.
The best part of The View is Hot Topics. People are talking about The View, more specifically what is being said during Hot Topics. And it's not just Rosie, both Joy and Elisabeth have made the news because of their comments.
Personally, I think Rosie has been a terrific addition. I don't agree with her all the time, but Hot Topics is all about their take on current events, not hard hitting journalism, so I'm not sure why people get so worked up about everything that is said. Rosie helped revive a stale show, so I can't see that her addition was anything less than a plus for them.
