10 Movie "Sequels" That Were Really Just Remakes
3. Vacation
The "Sequel": The original movie's young Rusty Griswold (Ed Helms) is now a grown man with his own family, and decides to take them on vacation to the very same theme park, Walley World, that his father (Chevy Chase, who cameos in this one) took him to in his youth.
Why It's Just A Remake: The core narrative is basically exactly the same, it's just the jokes that have been modernised. Granted it's not the most ambitious premise for a film, but that honestly just made it that much easier for Vacation to include references to and cameos from the original while touting itself as basically Vacation: The Next Generation.
When you've got a formula as winning as the Vacation series, why bother risking it on something new when you can just repeat what came before?
