Lost premiered back in 2004, basically kick-starting the Golden Age of Television. Over the course of six seasons and 121 episodes, it raised more questions than it was eventually able to answer, which led to a divisive series finale. While some fans loved it for staying true to the show’s central themes, others loathed it for failing to provide a satisfying conclusion to all those compelling mysteries.
Regardless of where you stand, you have to admit that the series was extremely influential, which makes picking the most important episodes of Lost a particularly difficult endeavor. What started off as an engaging drama about the survivors of a plane going down quickly evolved into a mind-bending sci-fi show that tackled larger-than-life themes, like faith versus science and good versus evil. To this day, Lost remains a layered and complex show - so much so that missing only a couple of episodes can leave any viewer scratching their head in confusion. The beauty of Lost lies in the character development, so if you’re planning a rewatch, we strongly advise you commit to all 121 episodes.

Regarded as one of the best TV pilots of all time, the first episode of Lost, a two-parter, does a tremendous job of introducing its large ensemble cast. It also hints at the supernatural nature of the island by giving the viewers a small glimpse of the Smoke Monster, having the survivors encounter a polar bear, and featuring the discovery of a mysterious radio message in French. Charlie’s "Guys, where are we?" line at the end of the episode was a surefire way to make viewers tune in to see what will happen next.Was this an important episode?
In the Season 5 finale, Juliet sacrifices herself in order to detonate a hydrogen device and wipe out the Hatch. That way, there will be no electromagnetic glitch to bring down Oceanic 815 in the future. This sets into place the flash-sideways concept of Season 6. We also see Jacob and the Man in Black and find out that Jacob interacted with the main characters sometime during their lifetimes. Plus, we get a sweet scene with Bernard and Rose, who are revealed to be living a peaceful life on the island.Was this an important episode?

Love it or hate it, you have to admit that the Lost finale has a touching message - the people who change our lives are more important than the answers we seek. In the last two episodes, the Man in Black initiates his plan to wipe out the island, while Jack tries to stop him. The meaning behind the flash-sideways device is also revealed. The survivors reunite and realize that they've all passed on, that their time together on the island was really special, and that they needed to find each other again before being able to move on.Was this an important episode?
The Season 3 finale of Lost is a gamechanger. For one, the plot on the island is pretty riveting. Charlie sacrifices himself to save Desmond and tells him that the boat they believe is coming to rescue them is, in fact, "Not Penny’s Boat." More importantly, we learn that the scenes with a disheveled Jack we’ve been seeing aren't flashbacks, but flash-forwards. Turns out, Jack and Kate make it off the island at some point in the future. Mind. Blown.Was this an important episode?
