I look at this picture and I’m wondering if this is a view Gilligan and his shipwrecked cohorts experienced every morning. If it was then why would they want to escape from the island? They were in a self-sustained paradise where every morning was tropical glory. True, they seemed to eat only coconuts and bananas. There must have been wildlife on the island. All they need do was get used to eating iguana (aka bamboo chicken) and catch a few fish from the lagoon.
If they really wanted to escape, all they needed to do was kill Gilligan. He was the one who thwarted all their attempts at escape.
