While I'm more of a Snake lover myself, I don't particularly hate Raiden. I suppose people have taken a disliking to him because he just didn't have that coolness factor like Snake. People probably hated his conversations with Rose to, since they were so long and...lovey dovey I guess. Its hard for me to say why since I don't hate Raiden but at the same time, I'm not his biggest fan. Though what I did like about playing as Raiden was all the stories he heard about the Patriots. My particular favorite was the one Emma told him, and of course the conversation between the messed up Colonel Campbell and Rose. Man...that last one still gives me goosebumps. The Plant chapter you could say definetly set the stage for the final MGS.
