This actually makes a lot of sense on the whole and sorts out a lot of problems with multiple cannons. Sorting out a proper origin for Unicron rather than the one which came up in the cartoon was probably the most interesting bit, as well as how it intertwined with elements from the comics like the Last Autobot.

The only real complaint I have about it is it still doesn't explain a lot of stuff from Beast Wars, such as who the Vok were etc.
