Typically, with any sort of entertainment–be it a movie, book, television or whatever–a certain amount of ‘buy-in’ on the part of the viewer is not only necessary, but mandatory.
By which I mean the person consuming the media has to suspend their disbelief–there are no orcs, zombies, dragons or psychotic AI’s–and invest in what they’re viewing on the screen, not matter how outlandish.
The same logic applies to more grounded entertainment. For instance, I am huge fan of Scrubs which is in it’s way as fantastical as anything that happens on A Game of Thrones, The Walking Dead or <Heroes.
Though sometimes I can’t suspend disbelief for reasons that are hard to quantify.
Like in the case of Voltron, the giant robot anime. For reasons I am not sure I understand I have no issue with the idea of a bunch of mechanical lions that combine to one massive robot, or the bizarre enemies they tended to fight from one episode to the next.
But for some reason I can’t get my head around the idea that the robot never managed to develop hands among the many other fantastical things that it does, and instead has to make due with lion’s heads (oddly enough, I’m okay with it having lion’s heads as feet, but find it off-putting when they’re used as hands).
That not to say that I won’t watch Netflix’s Voltron: Legendary Defender though I will continue to gripe whenever those dopey head-hands are on screen.
