I'm a fan of Green Lantern, but I'd say it's more uncomfortable than painful. For me the ride packs major forces into its small frame, and love that type of ride. I do wish the restraints were more comfortable.
And in fairness to the park currently, I do like the fact that Full Throttle is opening with an update to the area, something I hope they do again when adding something new. I think that's the best idea they've had in years.
