I agree, last year's Halloween was a let down but at its best it is such a fun season with so much to see and loads of villains out and about that only come out in this season. I hope that Disney noted last year's dissatisfaction and this year will be back on track.
I just think that as in the same way that we just have the DLH to stay in now, I like to leave the best to last so would (and did) do Halloween before Christmas. They are, or can be, both fantastic seasons but Halloween does at least have the advantage of better weather on the whole.
