Favorite season(s) would have to be, without a doubt, New Orleans and Miami.
First, I loved New Orleans for Melissa. She was my absolute favorite! What a nutjob, and so pro-gay... I LOVED her. I loved Danny too, but that was at a whooole other level. I was borderline OBSESSED with him, so... let's not talk about that. Favorite scene of the season was the very first time Paul came to see him Danny (episode 2, I think) and he was hiding in the bushes, shaking. Danny went out to comfort him and bring him inside as "Back To You" by John Mayer played in the background. So dramatic, romantic, and sweet.
Miami kicked ass, too. Remember the huge bitchfight between Dan and Melissa? Whoooa! There on the stairs... it was intense. But my favorite scene of the season has to be from whenever Flora, Sarah and Dan heard sex noises and moans coming from inside the bathroom. So, what they did was ran outside to the bathroom window and tried peeking in, but they couldn't see anything. As a result, Flora ended up letting Sarah and Dan hoist her up in through the window, but her boobs were too big for the skinny slats to fit through, so she ended up falling and breaking the glass everywhere... she was sooo BUSTED, LoL. I loved it! They were all cracking up. And then Cynthia talking about how if she'd been there when all this was going on, she'd have whipped out a bottle of holy water and thrown it on all of them while screaming, "Y'all goin' to hell! Y'all goin to hell!" Absolute hilarity.
Later seasons of RW became pretty boring. They started casting younger, so there doesn't seem to be a mature, relatable brain in any cast anymore. They're all obsessed with sex, booze, sex, booze. Nobody deals with any issues anymore. It's gone from being a topical program that addressed many issues to just being a more PG-13 version of "Girls Gone Wild." I definitely like the older casts.
