Yeah, a magic ring dosen't make a movie. Besides, any villian with blonde hair or a yellow suit is completely resistant to the Lantern Ring. What kind of ring won't affect anything that's yellow?
The very first supervillian Hal fought was all yellow. This is Legion. (Later reconned out though...)
One of his recurring villains was Goldface
Staements like that seems to tell me one of two things.
1. The person who said it, might only know the character from a t.v show or movies. Those really aren't the best source of information on the character. For example, Aquaman is often thought of as a joke because most people only really know him from the old
Superfreinds cartoon show. In the actual comic, Aquaman has superstrenght, reflexes, senses, and can really hold his own with the rest of the JLA.
2. In the over 40 years that some of theses characters have been published, why do people assume that no writer has ever devised a story line to exploit an obvious weakness?
Sorry, some of this is coming from a Green Lantern fan getting annoyed. You should have seen me during the Hal vs Kyle debate back in the day.
