I find the current event underwhelming as well. The pumpkin heads are from 1.0, so new stuff includes the decor, the ghost piece (with 2 faces) and a short quest line. In total, I got 1 hour of enjoyment out of it (including waiting for the quest to unlock). Even the 1.0 event was better than that (with the imps asking you questions etc)

I had hoped for something which lasts longer. Modifications to the overworld, not just the cities, and / or incentives to leave the cities to do stuff somewhere else. But I consider this a minor event, and am hoping for the starlight event to be of a greater scale.
