Getting more into the realm of guilty pleasures.
Push and Jumper.
Columbiana and Lucy.
La Femme Nikita and Leon: The Professional.
TMNT: Secret of the Ooze and the Mighty Morphing Power Rangers movie (the first TMNT is great, but for the tone, SotO is a better fit alongside MMPR).
Anaconda and Arachnophobia.
Street Fighter: The Movie and DOA: Dead or Alive.
The Shadow, The Phantom, and The Rocketeer.
The Craft and Empire Records (based solely on both featuring Robin Tunney).
Ghost in the Shell (the anime movie) and The Matrix (just to show how much they ripped off the anime movie).
The very first X-Men and Spider-Man movies.
The Equalizer and John Wick.
Armageddon and Deep Impact, or Dante's Peak and Volcano.
The animated Transformers movie and the animated GI Joe movie.
Girlfight and Million Dollar Baby.
Any combination of Clerks, Mallrats, Chasing Amy, and Dogma (technically, not sequels, just shared universe).
