I've really enjoyed the event thus far and rate it up there with the stonecutters event as far as prizes go.
It too had us clicking around the clock for the prizes (reminds me of the mouse navigating the maze for cheese)
At the end of each prize track we've had lots of time and opportunity to collect donuts and the pace is reasonable for a event lasting this long. Its been neither too fast (not enough time to collect what I want) or too slow (too much time between collecting stuff).
We've had a level update and a tie-in as well during the event which while providing more questlines to untangle and do, has been easy to put on hold until the event is over. In the case of the tie-in, it was short enough that I can hurry through it before it ends and the prizes from that disappear - a whole week before the phase 3 portion of the event ends.
Cecil and Bob are iconic characters to be released and they have done a fine job releasing them.
Of course, not everyone is going to be happy with a given event and there are people who complain about every event, but overall, I have found great enjoyment in this event...despite tapping as often as we have been.
