I have one issue with Generations; William Shatner agreed to the death of Captain Kirk. You do not kill Living Legends. All of my respect for him has drained away because he made himself a part of that idiocy. I've grown so cold about this I no longer see the scene as the death of Captain Kirk, it's now the symbolic death of my respect and admiration for Shatner.
Otherwise it's great, warts and all!
Concerning the Ent. E, my liking of the D waned greatly after the premier of the E. I began wishing the design of E had been used for the D because it's such a logical evolutionary extension of the TMP/1701-A refit, imo.
