Forcing myself to watch more films in batches of 3. Doesn't have to be an official trilogy but must have a unifying theme. Feel free to recommend your trilogy of some sorts.
(1-3) Batch #1: So Bad, So Good
(Notorious movies that are so divisive that there is no middle ground for the average rating scale.)
(4-6) Batch #2: Well-Known Tales, Lesser-Known Adaptations
(Underrated live adaptations of prominent fairy tales from the past.)
(7-9) Batch #3: Tickled Pink
(A film genre called Pinku Eiga (Pink Films) that captures the Japanese society through violence and eroticism)
(10-12) Batch #4: Prologue to Daft Punk
(Films which influenced Daft Punk, produced by Daft Punk, and directed by Daft Punk)
(13-15) Batch #5: Tetralogy Instrumentality Project
(First three films under the Rebuild of Evangelion. Preparation for the release of 3.0 + 1.0)
(16-18) Batch #6: Rhythmic 70s
(Critically-acclaimed musical films from the 70s.)
(19-21) Batch #7: One Hit I Wonder
(Directors having only a single movie shelved in their entire filmography)
(22-23) Batch #8: Liar Liar
(See how Pinocchio evolved through time in motion pictures)
