I've heard this word several tiles here and it always makes me cringe: "Synergy". I can imagine it being tossed around film studio boardrooms by clueless pitchmen in suits (and beards) as if it is the definitive justification for every lame idea thought-up in Hollywood, (and Burbank). Synergy gave us the Imagination Institute, Nemo in the Seas, Donald in Mexico, and all the other ill-fit intrusions that have been discussed over and over on these boards. It's unfortunate that people are willing to be so forgiving on theme just to get anything new and fresh.
I'm a proponent for more attractions in WS, and I know that travelogues are no longer the answer, but I would rather see something more creative and more interesting to adults than yet another truncated cartoon movie IP. I have no doubt that the rat ride is going to be a fun little adventure but it's honestly not a good fit for WS despite the "synergy" it may create -- (the premise of the ride only extends Disney's creative streak of something "BIG" being novel). I am really wondering if Disney is ever again going to move outside their comfort zone on an attraction so we may once again be pleasantly surprised by something that challenges both our imagination and intellect.
