Most games that are rated bad have technical problems. This one the developers must have intended to be this bad.
To be fair I'll list what is right about the game first. The graphics are all beautifully done, and you'll get a nice hands on look at areas in the island. The music is excellent and always complements the action. The voice work is also done well, but they did not get the actors from the show to do their characters (a glaring omission in my opinion).
Where the game fails in the completely horrid gameplay. The game consists of very few sequences repeated over and over. Though you might have fun a few times switching fuses around, you'll be entirely sick of it by the end. The worst thing they can have you do is walk through an unlit cave. You'll find yourself retrying these section over and over again because of annoying deaths caused by walking into a hole or running out of torches and being killed by... the dark, I guess. Most of the rest of your time in the game will be spent running around the island trying to figure out who you have to talk to or what specific item you're supposed to click on or the correct path you need to walk on. It doesn't take any skill just patience.
There is one redeeming section of gameplay and that is in the flashbacks. Your job it to recreate a photograph you're only shown parts of. It isn't hard, and only take a minute usually, but is more fun than the rest of the game. It is also the primary way the main character's story is revealed.
Of course the good of recovering your memories is totally washed out by one MAJOR annoyance. At the begining of every chapter, and every time you continue your game, it will show an unskipable scene of what happened "previously on Lost". Like you hadn't just played through it only a second ago! Since the chapters are only about 10 minutes long these 1-2 minute reviews are extremely redundant and only serve to frustrate you enough to put off finishing the game until later, at which point you'll still have to watch the scene again.
Despite well made graphics and sound it is hard to have good feelings about this game. Honestly this game would be better if it just played itself and you could set back and watch it (considering its based off a TV show, that kind of makes sense). The gameplay is at best boring and at worst completely frustrating. Even if you're a fan of the show or looking for easy achievement points, you should avoid this game.
