I heard from a good friend quite the opposit. Many questions are left unanswered, even those from the original game. Episode one starts, according to him, well. In episode two, new characters are introduced and, as he said, it feels like another exposition of the story, just like episode one. The story goes into a direction which would probably conflict with the canon established by the original game and episode three turns this effectively last minute with bad effort. And instead of answering questions and providing additional background you're basically left with even more answers – and worse graphics, animations and voice actors.
Some negative reviews on Steam confirm what he said. However, these reviews are heavily downvoted.
I haven't played it buy myself but I'm planning to do so nevertheless. This is a small just-in-case that you should fuel your hopes delicately and allay your expectations.
