----------Warning Spoilers Ahead-----------
Read my review of
Season 1 if you haven't watched it yet.
Season 2 of Lost focuses on the hatch that was discovered in Season 1. The first episode reveals that a man lives down in the hatch which is filled with all the normalcy of life off of the island. It's also revealed that the hatch is a station that "saves" the world.
If you thought that the cast of Lost was huge then get ready because there are survivors from the tail section of the plane. An episode actually shows what happened to the tail section survivors for the first 48 days. I thought that it was a clever way to get the audience invested in these new characters by showing how they struggled even more than the other castaways.
Another new character is Henry Gale. (I love the Wizard of Oz reference) He got to the island from a hot air balloon and got caught in a net trap. The castaways immediately think that he is lying and that he is an "Other". So they put Henry in the hatch as a prisoner until they figure out what to do with him. One of the big reveals of the season is that Henry Gale is actually Ben, who is the leader of the "Others". The other big surprise is Michael coming back to lead Jack, Kate, and Sawyer into a trap so he can get his son back.
This season was really great. It didn't lose any steam from the first season and all the new characters added a lot to the story. One problem with Lost is that they produce so many mysteries and don't get around to explaining any of them. This season adds even more secrets that will probably never be revealed but I guess that is also the fun of the show. They leave some stuff up for the audience to interpret.
My favorite part of this season has to be Michael Emerson who plays Henry Gale/Ben. He really raises the bar for the acting on the show. I still think Season 1 is my favorite but this comes close. I just loved the unraveling mystery of the hatch.
9/10
