In addition to the general review about GI Joe: Retaliation, I will add that there are a few moments that made me pause, from an epileptic perspective.
The first is an early fire fight. As a reminder, I’m more audiosensitive than photosensitive, so the automatic fire makes my brain a bit fluttery. There is also a bit of explosions (no surprise there, I hope) with flickering light effects an obvious part of that.
The second, and the biggie, is that at one point a character takes another character’s retinal scan, and the scanner that they put up flickers blue and red. The second I noticed the colors, I put a hand up over my eyes, I don’t play with that stuff. Because I hid from it, I can’t say with any certainty if it would cause anyone any problems. The flicker-rate for stuff like this is pretty closely monitored, post Pokemon-gate (lol), so I wouldn’t think it would twitch anyone out unless you had high photosensitivity. In which case, the first is just as likely to get you.
