Screenshots, sound bites, and thoughts on the episode:
The only questionable bit is how Lone Wolf seems to run and hide whenever he's in trouble. He doesn't seem to have the strongest character. Uncle Jack had to guide him to do the right thing.
DMarks also has reviewed the Land of the Lost movie. He notes one Native bit in it. An architectural model of a casino sports a chief logo with a face like Chief Wahoo's.
