Love You To The Stars and Back is a film that takes on a mature vibe. Compared to Vince & Kath & James that is fluffy and quite the romantic, Love You To The Stars and Back talks about two youngsters and them questioning life and whatnot. From the get go, it doesn't sound like they have any similarities.
It may not have the same premise and story, but it does star Joshua Garcia and Julia Barretto.
If you're willing to see more from those two after VKJ, then I highly suggest this movie :)

The movie Can't Help Falling in Love showcases Kathniel as an accidental married couple. The movie's biggest resemblance to Got 2 Believe is perhaps Gab's (Kathryn's character) dislike of happy-go-lucky Dos (Daniel's character), similar to Toni's (Claudine's character) dislike for Lorenz (Rico's character).

Vince & Kath & James also shows the hate-love relationship between Vince & Kath, our main couple.
The story's most memorable lines are also derived from Got 2 Believe, because Got 2 Believe is both Vince and Kath's favorite movie
