"The Infinite Vulcan" gets a lot of flak but I like it, too.
I don't know why clone Spock has to be fifty feet tall.
I have no problem accepting it, if there was a reason.
The Eugenics War scientist who still survives by cloning himself after centuries? And is still up to no good? That's interesting and good. And sentient plant life? More interesting aliens that no other Trek has ever attempted.
New and unique ideas there, I like it.
