I have the same feeling about it that HydroGuy has. I am looking forward to Captain EO (though not sure how "limited" its run will be?), even though I thought it was silly when it was there before. I don't know how many times I sat through EO and put on those purplish 3-D glasses, but I didn't love it. I just tolerated it. However, now that it has been gone for a while and HISTA bores me to tears, I am glad to see something new (old) replace it. I didn't realize HISTA was gone forever, though. I thought there may be a chance of it coming back after EO leaves again. I won't be sad if HISTA is gone forever and never returns!
If they can't get Mickey's Philharmagic in there or something new and exciting, hopefully DL can hang on to EO for a while in the interim, as I have a feeling it will continue to be a very big draw now that MJ is no longer with us.
