Hollyoaks (2006-2008) - It was amazing in those years and was jam-packed with drama without it ever being too silly (unlike now). The Dog Fire was especially fantastic. The week started with an aerial shot of four or five body bags which immediately built a lot of suspense and anticipation. Sarah's parachute death was shocking and emotional at the same time. The twist and the fall-out was just so sad. Hannah's anorexia was probably the stand-out storyline though. It was really upsetting viewing and the actress was phenomenal.
Emmerdale's had its fair share of great moments too. The storm in the early 2000s where Tricia died was upsetting. Then there was Shelley's death on the cruise, Jasmine and Debbie covering up a murder, Aaron's coming out and Jackson's death.
Eastenders has so many amazing moments. The Danielle/Ronnie climax is up there, as is Zoe/Kat reveal, Kat head-butting Roxy (Zoe's pimp), Stacey's bipolar episode, Stacey and Jean, Lucas pretending that Denise was dead, Stella, Den's death, New Year's Day 2015 episode, Lauren and Lucy going out on the town, Abi telling Tanya, Max and Lauren home truths.
