EW.com: 26 Great TV Season Finales

Here are the shows that I watch:

Mad Men

Ch-ch-ch-changes, Season 3

We'd gotten so comfy in the offices of Sterling Cooper that the finale decision to form a breakaway agency, Sterling Cooper Draper Pryce, felt downright revolutionary. Combine it with Don and Betty separating, and it was clear that the future of every main character was suddenly unclear. —KT

Alias

Two Years Gone, Season 2
J.J. Abrams gets props for his jaw-dropping cliff-hangers on Lost, but he perfected the art of the season-ending mind blitz on the less popular (but equally as compelling) Alias. In the final act of season 2, spy girl Syd's world gets rocked: Her best bud Will might be dead, her best girl Francie is actually an evil clone, and there's the small matter of two missing years. Not to mention a smokin' hot Vaughn sporting a mysterious wedding band. You'll be hit so hard with the Alias title card it'll give you whiplash. —GH

Grey's Anatomy

The Heart Can't Go On, Season 2
Thought a lot of people were gossiping the day after your prom? Try 19 million people. That's how many fans showed up for Seattle Grace's second season finale/two-hour, prom-night bonanza spectacular — a heart stopper, and I mean literally. Denny got a new heart, gave it (metaphorically) to Izzie, and then promptly flatlined, leaving the doe-eyed intern not only dateless and devastated, but possibly jobless. Meanwhile, Mer and Der put a whole new spin on the term ''examination room,'' in one of the raciest sex scenes to sneak past network censors to date. Who would Meredith choose: McDreamy or McVet? Better question: What would become of Mer's McMissing underwear? —GH

Friends

Ross Comes Clean About Rachel, Season 4
When Ross said he'd wed thee, Rachel, instead of soon-to-be wife, British bore, Emily in "The One with Ross's Wedding, Part Two," all the pro-Rachel-and-Ross Friends fanatics freaked out. Sure this was what we had all been waiting for in the on-and-off-again relationship between the high school bittersweethearts, but at the end of the fourth season?! Too soon! We needed six more seasons of slamming doors and coffee-shop kisses — and a deliciously agonizing wait until "The One After Ross Says Rachel." —Lisa Raphael

Stolen from here.

Damn, I really miss Alias and Friends! Haven't watched them in a while...
