I see very little similarity, both in the story and in the art style.
I am not sure if it will have the same type of endings, or if it will follow a different way.
But, while not ALL the endings of the other game were bad, the method used to get to the endings, indeed sucked.
What I do like about this story is that you do have to pay attention to the clues that are shown and talked about, in order to truly understand the story. I have to tell you that many users in this thread completely missed the point, or, interpreted the clues in a nonsensical way. Or, maybe I'm the one misinterpreting. So, I will not tell you what I DO think about the game. I can only tell you that it is very interesting, has great characters and a cool story. The rest, truly, is up to your interpretation. I do recommend to play it with both eyes open and a critical thinking cap handy. Also, don't jump on first impressions, they are really there to deceive you.
Have fun mate.
Peace
