As for a link, here you go:
In 2005, after Schumaucher and an eight year absence, people were starting to grumble about the voice. But as you can see in the thread, fanboys are like, "I liked the movie and Bale is great...but the voice seemed....forced. STILL GREAT!
By 2008 it's, "The movie rocked, too bad Bale's voice is silly."
In 2012, fanboys realize the series is over and there is a new shiny toy around the corner and it becomes, "That voice sucked! And so did the movie! GRRRR!"
It is just the way this cycle works.
