Quoted from Captain_Kirk:The Well Walker was an iconic Zombie from that episode. The other is scrawling on a helmet for 2 seconds. Not comparable.
I guess that's debatable & subjective to what one feels is important, now isn't it? One could argue that the Well Walker plays a smaller roll in the The Walking Dead series, than the "saying" on the helmet in Aliens. TWD spends 10 min. of one episode out of a 6 Seasons series out of a Total of 83 episodes(3735min). As compared to 2-3 seconds of 1 movie totaling 117 minutes.
My archaic math says that: the helmet saying plays about 2.5 Times the significance in "Air Time" as the Well Walker scene when looking at the entire scope of both, & the time committed on screen.
Obviously the Well Walker was a unique zombie, but to say that the helmet saying on the playfield was a crazy idea, is just silly. It's different & unique, but it plays a role in the overall theme of this pin.
