I'll be Ranking the DB movies on different ranks below. (If your wondering, I watched the American Versions of The DB Movies)

Best OST: DBZ: Cooler's Revenge, DBZ: Broly The Legendary Super Saiyan, DBZ: Lord Slug, and DBS: Broly. These 4 movies in my opinion have the best OST, Mostly the DBZ Movies because of the music Involved are from some of my favorite bands like "Haiji Kitchen", "American Pearl", "Boy Hits Car", etc. (It could also be because I'm a huge Rock and Metal Music Junkie) DBS: Broly has a beautiful OST that really captures the masterpiece of the film.

Favorite Movies: DBZ: Broly The Legendary Super Saiyan, DBZ: Cooler's Revenge, DBS: Broly, DBZ: Super Android 13, and DBZ: Fusion Reborn. These 5 Movies really impacted me with their over-all plot and interesting Villains, Broly, Cooler, Super Android 13 and Janemba were all very interesting villains in my opinion. When DBS: Broly was announced, it made me very excited since that Broly would finally become cannon.

Worst DB Movie: Well we all know what would go here, but since I didn't re-watch Dragon Ball Evolution I'm putting Bio-Broly here for personal reasons. They turned one of my favorite DBZ Movie villains into a pile of greenish brown shit, just like the movie. looking at you Takao Koyama, even though you've screen written some of my personal favorite DB Movies, Including DBZ: BTLSS, DBZ:CR, and DBZ:SA13, you still screen writ Bio-Broly so I can't forgive you for that.

Favorite Movie Scene: In DBZ: Super Android 13, when Goku goes to kick the super android, 13 grabs his leg and punches Goku so hard in his balls, it forces him out of Super Saiyan.

If You look closely and pause at the right frame, you can see at the moment 13's fist reaches Goku's groin you can see two eggs crack. Nice Attention to Detail

Best Animation: 1st place definitely goes to DBS: Broly, I mean it's gorgeous. 2nd place would go to DBZ: Battle Of Gods mostly because of the amazing battle in the sky between SSG Goku and Lord Beerus, 3rd place would go to DBZ: Fusion Reborn. The overall environments of Fusion Reborn are beautiful, and let's not forget Janemba's dissimulation technique that was animated beautifully by Tadayoshi Yamamuro himself, he even stated in an interview that this was the hardest thing he ever had to animate.

Memorable DB Movie Scenes: Goku Going False SSJ, The Family Kamehameha, Broly beating the absolute shit out of the Z-Fighters, 13 Punching Goku in the Balls, Janemba's defeat, Android 13 calling Future Trunk's hair-style a "30$ Haircut", Zangya's Death, and Cooler giving Goku a Beat-down.

Welp that's if, I hope you enjoyed reading this, (if you did) this was a fun experience re-watching all the DB Movies again.
