'Pretty Little Liars' Season 4 Finale: Who Is A? And 24 Other Reasons We're So Addicted

'Pretty Little Liars' will close off their Season 4 finale with the one question we keep asking ourselves over and over: "Who is A?"

No really, who is 'A?' It has been four years now (the show premiered on ABC Family in 2010), and with every clue revealed and black hoodie we've seen on-screen, we're not any closer to knowing the true identity of 'A.'

And while the spring finale of Season 4 airs Tuesday, we sometimes have to question why a show full of cliched plotlines and teenage drama (we're both in our 20s), has us on our feet every single episode.

Watch "Pretty Little Liars" on M3 at 8 p.m. ET/5 p.m. PT in Canada and on ABC Family in the U.S. at 8 p.m. ET/9 p.m. CT. on Tuesday, March 18.

Here are 25 reasons why we can't stop watching 'Pretty Little Liars' ... and why we don't plan on stopping any time soon.
