Nope, you are not alone!! I have nothing but disdain for the new Fozzie puppet - I genuinely hate it, which is quite well documented on here.
Like yourself, Fozzie used to be one of my favourite characters but I no longer care for him anymore. These days, the Puppet looks way off and his character isn't right - this is no reflection on Eric's performance, it's more down to the writing.
With regards to how he now looks, the excuse of "no two puppets look alike" doesn't really hold water with me. During production of "The Muppets", Disney made out that Fozzie's fur was no longer available and Puppet Heap had to find something similar. Sadly, I can say with 100% conviction, fur the same as Fozzie's or close enough for nobody to tell the difference is readily available, I know this for a fact. This has left me of the opinion this change is 100% done on purpose. Like D'Snowth mentioned, I too have drawn the conclusion that this is to soften the character and make him look clean and more like a stuffed toy - which is probably done solely to push merchandise and appeal to the younger crowd. However the issues do not stop at the fur. His head sculpt is awful, I can't stand his new "fat" jaw and his eye focus is simply dreadful - he looks spaced out for the majority of the time.
I think there has been a lot of "Disneyfication" of the Muppets appearances, though not all bad. Overall, the characters pretty much all look incredibly pristine now, unlike the rag-tag bunch of characters from the original Muppet Show. They all looked like they had seen better days, which I preferred and felt it gave the characters more of an edge. But, at the end of the day, Disney owns the Muppets, has done a great deal of good with them and can do with them whatever they like - they are not gonna lose sleep over what this fan thinks. After years of bad incarnations, Piggy now looks great, Scooter has never looked better and we have recently seen many of our favourite and beloved obscure characters from yesteryear brought back and re-built, so I guess we must accept the rough with the smooth.
That said, I really wish they would change Fozzie, I've yet to hear of a single fan, though I am sure someone will quickly jump in and prove me wrong on that soon enough.
