I've seen all four Ring movies (3 Japanese and the Hollywood one) and they barely made me flinch. I saw The Butterfly Effect and had nightmares for a week. The most disturbing movie I've ever seen was Home Alone 2. Maybe that sounds backwards, but the violence in that movie was shocking.
I was watching episode 4 of the new series again, and I noticed this interesting scene on the holographic ship:
Astro turns to the right and we see his spikes from an odd angle. They're not normally drawn like this, but I guess they had to working things a bit different to account for his head turning.
