The pining for Moviefone really undermines their messaging, to the point where I think it can be dismissed entirely despite the general idea that media browsing UIs for streaming services suck.
First, there's the "OK, boomer" aspect of Moviefone. I'm in my mid-40s and never once used the service, but maybe I'm an outlier.
Then, there's comparing Moviefone and the newspaper listing showtimes for the 5 movies showing near you, to the listing of hundreds, thousands, or tens of thousands of pieces of media in a format that makes discovery even remotely possible. Utterly incomparable to begin with.
If you just want a listing of movies showing at your theater, call your theater and ask. Or go to any of countless sites that list movie showtimes, including your local theater's.
Don't undermine your messaging by opining for what was obsoleted 20 years ago and wasn't exactly good to start with.
