Being a "replacement" puppeteer is rather thankless and difficult role to fulfill, having to take over the voice and personality of a popular character. So I don't critique the performers too much. I think a lot of the critique is more with the writing rather than the performers themselves. There has been an overall attitude change that not everyone likes (and they don't have to). Not just because it's different, but because it doesn't seem right. Of course I'd rather not "blame" anybody. It's very difficult trying to recreate Jim's work and I commend them for making the effort.
