Get over it Mr McFeelings. Your idea was a tad on the brainless and thoroughly improbable side, so logically speaking no explanations were really required for accurate disagreement. Being called an idiot shouldn't ruin your day. Besides, Raveers apparently likes calling people an idiot from what I can tell so I wouldn't take it too personally.
Just to make you feel better, I'll give you a few reason for disagreeing. The very large and green stack of cash they allready spent on making the 6 actual movies for starters. I guess another reason could be the fact that such a project would itself cost a huge amount and many fans would be over the novelty of it half way through the first film. Re-creating all 6 films in this animation style would be a humongous waste of money and time and effort, all of which could go into something more entertaining and lucrative. It's bad business, it's bad storytelling, and defending such an idea is just bad sense.
Feel better now?
