Ranking 9 Biggest Two-Part Movies From Worst To Best

9. Divergent: Allegiant

In what has to be the worst and most embarrassing case of splitting one story in half to produce two films in cinematic history, the struggling Divergent series was unable to even complete its story.

Taking cues from the success of franchises such as Harry Potter, Twilight, and Hunger Games (we'll get there), the producers behind the Divergent films opted to split the final book of the series into two separate films. However, the first part of this grand finale was such a complete and total disaster at the box office. Thus the planned follow-up, Divergent: Ascendant, was permanently shelved.

What audiences were left with was half of a story, that was just build-up, without a second half to ever capitalize on it. On top of that, Allegiant was made from the barest story possible. The final book in the series barely has enough material to fill one film, much less two of them. So the producers were really stretching to try and make it into two films, and the result is that this film is full of moments just there to pad the runtime up to feature length.
