I'm partially in the "wait-and-see camp" (because I really do want it to be good), but still very much in the "whyyyy" camp. There are so many other stories to adapt (still waiting to here more about the Wizards of Once adaptation) and so many original stories to tell. Doing a remake of an adaptation only 15 years later just seems like overkill.
I think DreamWorks' best work is in historical fiction, folklore, and fantasy (Like Prince of Egypt, Shrek and HTTYD are hands down their best stuff IMO). They could make some amazing stuff if they tried new narratives in those genres instead of desperately rehashing and sequel-ing every single successful franchise they've done in the past.
