While many TV episodes are infinitely rewatchable, some are too tough to watch more than once. It's easy to want to revisit clever classic sitcom episodes like Seinfeld 's "The Chinese Restaurant," and some dramas reveal new insights about favorite characters upon a second viewing. That's one reason why it's so enjoyable to watch the cozy Gilmore Girls each fall .

Unfortunately, not every show can be rewatched the entire way through. Despite their high quality, these episodes from a popular sitcom, a dark comedy, an impressive medical drama, and a shocking thriller can only be seen once, thanks to their off-putting, disturbing, or emotional nature.
