Turner and Hooch is Touchstone. They have Ice Age TV show though, but it's bizarre they don't have all/most of Blue Sky content and Fox Family stuff (like Home Alone). The new content is tied with HBO until 2022 IIRC, but my guess is a) That content might be tied somewhere else (like some of Disney's own stuff that wasn't announced for launch) and b) they are probably waiting for a second wave of announcements when a lot of this missing content starts magically appearing and then they get more subs.
Dude, spoilers! That's like the major part of the movie. That is the best Benji movie though, for sure.
