Typically speaking this is the argument most sub fans use...
Well actually the typical one is
"GRRR!! WHAT HAPPENED!? THEY SOUND LIKE FAGGOTS! ALL THE EMOTION IS GONE! I'M NOT FEELING THE SAME THING FROM A SHOW I'M RE-WATCHING IN A LANGUAGE I DIDN'T UNDERSTAND!"
Typically you don't re-watch a dub of a series to feel the same way you first did when you saw it. That's impossible by the mere fact you're re-watching it.
