^Yeah, I've been debating warning people about that. I almost bolted from the theater when I saw the Planet of the Apes reboot a couple years back. The caregiver scenes with John Lithgow's character poked at wounds that were still pretty raw. I even had problems with the death of a character in Trek 2009 when my wounds were still gushing, but I still saw the movie about three times.
I weathered the GOTG opening scene a lot better than I thought I would.
There was a Christopher Lee horror flick I saw on tv in the 70's the title of which eluded me until TCM ran it one Halloween a few years back. All I was able to recall of it for years was a castle full of people being turned into statues by a mad scientist fellow.
As for GOTG itself. You'll believe a raccoon can cry. I loved it, and bought the soundtrack same day I saw it. (Nobody told me there was a two disc version with the score though!) See it in IMAX 3D if you can.
