For me, it depends on the first episode, which tells you everything you need to know on whether it's dub or sub, that's better.
And thanks to finally seeing the OP, I'm adding Tokyo Ghoul to my list.

It turns out it was only the Tokyo Ghoul GIF that seem to give any trouble for an unknown reason. I basically just copy the not loaded image and view it by itself. I'm surprise there's any problems at all, I mean you don't got much in the OP.
Im surprise the OP gave me any trouble, my OPs per OP have way more images, and embedded videos. While yours just seem to have a dozen or so images.
Anyways, thanks, I've finally got to see the OP, including the one active GIF: http://giant.gfycat.com/DeepSneakyLarva.gif
