When it comes to television shows, cliffhangers are extremely important. Used as a way to keep audiences coming back for more, an exciting cliffhanger has the ability to make or break a show. This week we are looking at some of the best cliffhangers from some of the most popular shows out there.

The final season of comedy drama Gilmore Girls was supposed to satisfy fans who had been waiting for nine years for a revival of the popular show.

Will there be another season released in the future? After a cliffhanger like that, it’s hard to believe there won’t be.

Friends was all about the cliffhangers but one of the most unforgettable, jaw-dropping ones was when Ross (David Schwimmer) was supposed to marry Emily (Helen Baxendale).

Ross and Rachel fans went wild and were left wondering if the pair would get back together, which they eventually did.
