I never hated Lee Ryan either. He annoyed me and pissed me off of course, but I never felt like he was ever malicious or mean-spirited. Quite the opposite actually, the whole triangle thing was bad but I think he was just a stupid, reckless, highly-sexed guy than someone intentionally trying to hurt people and when you put that aside he was one of the nicer ones imo. Not a defence, he absolutely deserved his criticism for it but I did think it got a tad disproportionate when people are treating him like he's just spent a few weeks kicking puppies to death.
Also, I think everyone involved should be judged equally. I mean, Casey ran right back to him after Jasmine left even after all of the trouble that had happened but then suddenly it's a "LEE IS EVIL, POOR CASEY" thing? In a nutshell, everyone involved was just being stupid and thinking with their private parts rather than their brains.
Also about Lee, I really liked his love for animals and loved his talks with Liz about it. It's one of those really nice, unexpected BB friendships (yes he nominated her but still

).
