I've been a Muppet fan since long before you were born. I think Master Replicas' Kermit is BETTER than some of the overstuffed posers that Henson Co. used. I've always hated those. And that Fozzie poser from Muppets Take Manhattan is horrible. I can't stand to look at it.
So, I take issue with your very premise. The real posers are all over the map as to likeness. I think these measure up and surpass some of them.
Even Gonzo, who I've been very vocal about disliking, is certainly no stuffed toy. Expensive toy, maybe, but I wouldn't call it a stuffed toy. It's lightyears ahead of any other Gonzo product ever made.
If you've seen any of Anthony's (KermieBaby47) pictures, I don't see how you can claim they don't measure up.
