I hated them in the theater too. If I had to choose between them or Devastator's balls... it's a tough call which was worse. At least the balls weren't racist stereotypes.They made people laugh a few times in my theater. The hate they got was definitely more of an online thing.
Except for the notable fact that Optimus has the Matrix in DOTM, which he only could have gotten from the events of ROTF.Plus the fact that it is basically contradicted by the first and 3rd movies making it irrelevant.
The first movie showed us the inside of his chest with no Matrix. And the Matrix's ability to restore life to Transformers kind of works against Optimus's intent on sacrificing himself with the AllSpark in the first movie.Not really. I would argue that him just having the Matrix all along with no explanation is better than the explanation ROTF provides.
