If you really want to write this story, there's nothing wrong with going back and revising it in a way that will make it more exciting and increase the pace. Writing is rewriting.
Having more POV characters--while super difficult--is totally acceptable if you have a sweeping epic (just look at George R. R. Martin). It's even acceptable to have multiple POVs in movies which tend to only be 2 hours (look at Tarantino's films--all of which are ensembles with tons of different POVs).
The trick is to really give each character something unique. The way to do that is to give them each a separate want (external goal or A story) and need (internal goal or B story). You already identified this in your thread as the missing piece to the story and why you think it's "boring". So go back and fix it, if you want to. It's totally salvageable.
My own story has 8 main characters and multiple POVs. It's really hard to balance them all but it will eventually break out to three separate stories all of which have the same overarching goal with separate "character goals". It's hard as hell to do and can be super confusing. But it's also a great way to practice multiple characters, voices, events, settings, etc. The other thing I would suggest is to keep a third person POV. I started with first person POVs and it wasn't work (a review also said that the reviewer found it distracting), so I went back and changed it. Again, writing is rewriting.
