I kind of agree. I like Snape as he is: a very not nice guy. My issue with book!Snape is that we are supposed to accept him as a good guy as if the good things he did (for the wrong reasons considering his feelings for Lily involve stalking behavior and wanting her husband and son dead so he could be with her) absolves him of his horrible actions and that somehow Harry would name his kid after him. In some ways, I prefer movie!Snape because I can accept movie!Snape as a very flawed flawed but ultimately good guy.
