While the prizes so far do seem lame unless you don't have Hugo or the Scary Dock + Blinky Monster, we still are in the first week of a four week event which is like the McGuffin act. The only items that have a connection with each other are Robot Homer, Monkey's Paw Salesman and his shop which appeared in the same episode. I hope that it does pick up more on Wednesday when act 2 starts.
The main good thing about this event is that the Bart screens seemed to happen less frequently and rarely. I also hope that the music appears with act 2 and possibly an item limit increase.
Christmas could be a better event or have something new since there have been times in the past where a Halloween event was disappointing then the Christmas event was so much better and vise versa, like in 2015 and 2017 with a disappointing Halloween and a great Christmas though others might disagree with this.
