Watching You Again brings me back to the times of watching Desperadas Parts 1 & 2 where good and able actors act desperately to save a desperate film. The concept was good enough, but it wasn't backed up by a good script. They had to rely on poorly-written antics and jokes that bordered on slapstick most of the times. Further, its heart was not in the right place. When the characters tried to make amends at the end, you'd barely feel for them. Even the main bully (Odette Yustman) in the film didn't know where to place herself properly. She seems to be suffering from split-personality wherein she goes back and forth into being a good person and a bully.
The last scene, though, between Betty White's and Cloris Leachman's characters were more interesting than the rest of the film. Too bad that it was just part of the epilogue. They had better lines than the main characters.
