I think an important distinction is to be made between the burning of Teldrassil and the attack on Autobot City during the 1986 Transformers movie. I hear people compare the two constantly. All the time. In my head. It has reached the point that I feel I need to make a few distinctions.
Granted, both are a shocking and tragic opening to their respective story arcs, but we must be aware of important differences when comparing the two.
For example, the attack on Autobot City was achieved through complete surprise, by the hijacking of an Autobot shuttle (and the immediate and tragic deaths of Brawn, Prowl, Ratchet, and Ironhide. Such foolish heroics indeed!)
Conversely, the burning of Teldrassil was preceded by a large scale assault through Ashenvale, which was resisted, despite the unexpected scale of it.
In the attack on Autobot City, the Decepticons are largely unstoppable, until the arrival of Optimus Prime, who single-handedly tears through the Decepticons before his duel with Megatron. During this duel, Optimus seems perfectly capable of winning, until his own subordinate, Hotrod, tries to intervene on his behalf, resulting in Megatron being able to mortally wound him.
In the Burning of Teldrassil, Malfurion arrives and blunts the Horde attack, before his duel with Sylvanas. Granted, much like Optimus, Malfurion seems perfectly capable of winning this fight, until the intervention of Saurfang.
The key difference here is, Saurfang is Sylvanas’s subordinate, not Malfurion’s, which is precisely the opposite arrangement from the Transformers clash! The situation is subtly but critically different!
While I understand the very human drive to draw analogies between events, to find understanding in similarities, we have to keep in mind that perceptions regarding these events can vary far more widely than one might imagine. As a result, at times?
This is bad comedy.
