By the time a kid is about 7 or 8 they will see the similarity between Darna, Captain Barbell and Lastikman
Wonder Woman, Captain Marvel and Plastic Man. Or somebody who is really brain dead will accuse DC/ Marvel of ripping off Mars.
b) Arnel Pineda-
most of my thoughts are here.
But to summarize all he is doing is mimicking what Steve Perry has done before him. Monkey see monkey do. Arnel, be a good boy and just copy Steve Perry.
c) Charice Pempengco-
Only answer if you are over 12. Name 3 of her songs. Now name the 3 artists that are better known for performing those songs. Monkey see monkey do. I really thought the "O" in OPM stood for original.
For me originality should count. It obviously did not matter for Manny Pangilinan.
