Excellent, probably the best in the trilogy. It's not really much of a "final entry to a trilogy" kind of deal, though that's only to be expected.
Personally I don't think the step up in graphics was wise, it adds a lot but it also makes the game incomparably harder to run, at the opposite end of the spectrum to its predecessors. It does look good though.
According to the achievements, 52.2% of players have the golden ending, which is a lot, and it's definitely much easier to get than the previous games. That's neither good nor bad though.
In a lot of ways, Lorelai feels like a mid point between elements of The Cat Lady and Downfall, though is ultimately very much its own thing.
