I personally think all the post Jim films got worse with each consecutive release. Treasure Island wasn't as good as Christmas Carol, and MFS was easily worse than either of them. For those who don't simply give Muppet films passing grades for including a lot of older characters, VMX was far below any of the previous theatrical films. Meanwhile KSY and Oz were definitely bottom of the barrel. The BIG upswing was the 2011 film, easily the best full-length Muppet product since Christmas Carol. Muppets Most Wanted, while also better than anything since Christmas Carol, wasn't quite as good. Personally, I think if Disney WAS to make another theatrical film, it would continue the downward slide.
