Mermaids & Megalodon...Has the Discovery channel lost credibility?

I am a fan of all things paranormal, metaphysical, etc., but when I watch the Discovery channel I expect a certain amount of honesty. Discovery has put out a couple of shows lately that just rubbed me the wrong way once I thought about it. Mermaids: The body found, & Megaladon: The monster lives. Don’t get me wrong, I think the shows were well written, entertaining, & thought provoking, but I didn’t like that they were presented as if they were factual. You know that there are people out there that now believe in mermaids because they watched that show. Which is laughable but also sad. There is plenty of subject matter that is “unexplained” but also genuine. Maybe it’s just me but I would rather watch a show with some real guy who really believes in bigfoot out in the woods hearing tree knocks & almost being hit by rocks thrown from just outside the cameras point of view than a complete fiction with c.g half eaten whales presented as non-fiction. Just my opinion.
