I can't speak for the first 24 hours, but I did watch the channel launch (I have Cablevision). Plus we've seen their channel lineup so far. Besides the so-called "Golden-Age" Disney shows that air 4:30AM-7AM each day as well as the movies, none of these shows were made for me thus I don't find them entertaining, BUT after all obviously, this is a preschool channel not a retro channel, so I wasn't surprised that there weren't a lot of old disney series being rerun from the get go. Though I was surprised that The New Adventures of Winnie the Pooh was NOT part of the lineup, maybe in the long run it will. Oh well, as long as they don't take off the older series, but that's mostly a personal preference. Though from a business perspective, they would want to run programs like Jungle Cubs or 101 Dalmatians during non-peak viewing hours, since very very few kids are awake from 2AM-7AM. Besides, Disney's preschool library is still small compared to Nick Jr.'s and PBSKids Sprout to successfully fill 24 hours. Personally, however, I'd extend the 'night block' a tad longer like this:
3AM-3:30AM Mickey Mouse Tracks (I'll touch on this next)
3:30AM-4AM House of Mouse
4AM-4:30AM The New Adventures of Winnie the Pooh
4:30AM-7AM (just to save time, I think we all know what already airs here)
Ultimately, however, the ONLY thing I would like to see Disney Junior reair are the full classic shorts, the 90s shows are just bonuses as far as I'm concerned (especially considering that the most popular Disney Afternoon shows are already widely available on DVD, unlike the classic shorts which are essentially limited and/or overpriced). Though, given the success of Mickey and the Gang among the little kids, I don't think this is too far fetched to ask for. Disney could at least air a repackaged series like Mickey Mouse Tracks, Donald Duck Presents, Donald's Quack Attack and/or Good Morning Mickey at say 3AM, 4AM maybe. We shall see...
Overall, even though this is a preschool channel, I will say this, I really like the vibe of the channel. When I was watching the launch, I felt like a kid again (until Mickey Mouse Clubhouse came on). I haven't seen Disney magic like this for many, MANY years on TV. Other than the old Disney shows and movies, I might watch this channel during the day just for the bumpers .
