Most of the time flops have had too much material cut out to hit runtime requirements ("nobody will watch a 3 hour movie!"). Kingdom of Heaven, Batman v Superman, Watchmen, Alien3 all get better with restored material.
Blade Runner is interesting as there are 3 different versions, all about the same length but with some very different scenes. Theatrical also has a terrible voice over which was later removed.
The Shining is one that gets better when shortened - most feel that the 119 minute European version is better than the 144 minute US cut.
Apocalypse Now is interesting - Redux (193 minute) is a slog compared to theatrical (147); but Final (182) is probably the best version and a great example of the balance needed.
There's also the video 'How Star Wars was saved in the edit' which has a lot of good information on what editing can do. The video has kindof been co-opted by the internet as definitive proof that George Lucas is a talentless hack, but it's really not that much different than what happens on every other film. https://www.youtube.com/watch?v=zEHRNS-Scrs
