The Book of Revelation: A Theological Bias

The book of Revelation is probably written pretty close to the turn of the century getting into the 90s AD right toward the end of the life of the apostle John. It seems very eager to get on to the apocalypse side, but it bridges the gap between the age of the church and the end of all things with these opening letters. This stuff reads pretty straightforward. But what I'm looking for is completion to this story. Is it good? Can I celebrate it? Is it a happy ending? Does God end up winning?
