I know what you are going to say "If it's not broken don't fix it" or "I like the way it is" or "The animation is what attracted me to the show" but lets forget that for a while and get strait to the topic.
If mlp was traditional animation instead of flash animation but had the same characters, personality, world, plots, colour and everything else would you still watch it.
IMO I would still enjoy it or maybe even enjoy it even more.
but that is my opinion, I am not saying they should swop to traditional animation, I just think it would be better to me but probably not to you.
tell me if you would or not I will not judge your opinion.
