I must admit, I'm really not liking Seany either. I got a bad impression of him at first, and it's just been getting worse. To begin with I thought he was rude in the DR, then he was stupid enough to tell Ziggy what he heard about with the Charley chanting, and then pulling the bedsheets off Lesley, who's 60+ - not even middle-aged! Highly disrespectful, not in the least bit funny, and it was the very first night he'd met her...not to mention he didn't make an effort with her when he entered in the first place. He needs to sort himself out if he wants to go far in this series.
I also agree with what you're saying about ordinary interesting guys possibly not having much of an advantage in terms of getting into BB. If there are more male housemates to come though, I really do hope that's what they're like, because I actually think that's what the majority of people want to see.
Welcome to the forum by the way.
