Bunch of personal opinions to follow:
I can’t see myself ever missing Food Rocks. That show was the first glaring, unavoidable neon sign that EPCOT was hurtling towards the abyss. It was the first time I ever experienced a Disney attraction and wondered what the creators had been thinking.
Now Kitchen Kabaret - that’s a show worth missing!
I understand and appreciate folks pointing to Land as a last bastion of classic EPCOT. The downside is that (glances around nervously) I always found the Land one of the least interesting parts of classic EPCOT, with the exception of the long-gone Kitchen Kabaret. If you had told me I could only keep one Pavilion from classic EPCOT, The Land would have been my second-to-last choice (my last choice would have been Seas, which is also, ironically, largely intact).
