Re: Scenes in the movie that made go "Uhhh really?"
There's really no rules to the Matrix except that it couldn't be found. It is earned. That's it. They never say it can't be physically destroyed.
Yeah, it technically was a sock of dust at one point before it became one again but still, Prime destroyed the Sun Harvester with the Matrix inside.
To me, it's done with and unimportant because the Autobots and Decepticons pretty much existed fine without the thing so it's not really relevant to their survival.
And yeah, I can't get past the retconned stuff in film. I mean, Prime's voice over can't even established how long they've been on Earth in relation to the last film. I couldn't even believe that piece of dialogue made it to the final film ("A year after our arrival?" WTF? How about four years after our arrival...)
