While The Lion King has its roots in Hamlet, The Lion King II: Simba's Pride is based on Romeo and Juliet. When Simba's (Matthew Broderick) daughter Kiara (Neve Campbell) falls for Kovu (Jason Marsden), a member of the outlanders that looks like Scar, all hell breaks loose. It's not until they're able to make their families see the error of their ways that things begin to change.
What makes this sequel worth watching is that, unlike most of the other direct-to-video offerings Disney has put out, the animation style is more in line with the original. On top of that, most of the original cast reprises their roles, including Nathan Lane, Matthew Broderick, Ernie Sabella, Robert Guillaume, Moira Kelly, and James Earl Jones. If that alone doesn't sell you, The Lion King II: Simba's Pride has some of the best songs, including "One of Us" and "He Lives in You," the latter of which was so good, it got included in the stage adaptation.
The Lion King II: Simba's Pride is currently available to watch on Disney+.
