I'd say the problem is Dreamworks's trying too hard not to be Pixar, yet also trying to keep it's identity when everyone and their mother has a CGI movie animation studio. Trolls was Dreamworks trying to go after that sweet sweet Alvin and the Chipmunks, Smurfs money and we almost had another bad Tim Hill film (no crap, he was set to direct and everything). I never actually sat through the movie "Hop" even though it was on Easter at some point somewhere (was too busy with the TMNT season 4 to this point marathon on Nicktoons), but, like Free Birds, it's one of those movies that says "there's a reason why there haven't been movies about this holiday." So Tim Hill's latest film was the Grumpy Cat thing on Lifetime, and that movie's essentially just a bad kid's movie with Grumpy Cat pasted in to comment on how bad a kid's film it is.
Now, I find it a shame Dreamworks is hurting. While I can say they had some odd non-sequel film choices that were audience alienating (though my sister swears that kids were really keyed up to see Peabody and Sherman, I think it paritally suffered coming out after a steady stream of stronger kid's movies), seems their big franchise hit films were the victims of poor timing. If Penguins of Madagascar didn't prove that the Thanksgiving weekend is a terrible slot for movies, Pixar's Good Dinosaur sure did. It's an all or nothing weekend with a steep dropoff the following week, and Big Hero Six was still around. KFP2 and HTTYD2 should have done better (and were actually considered hits overseas, and I don't want to go through that rant again) but somehow lost to comedy sequels basically made to comment on the fact that comedy sequels don't work. KFP3 did well for January and got most of its business from China who they made the film for. But other than that, they frantically swapped around, pushed back, and essentially sat on movies because they aren't making the Shrek money they used to.
Though, in terms of POM the movie, I have a feeling they knew the film was their sacrificial lamb. They swapped the date with Home (and at least Home did well domestically as a result), and even the Happy Meal tie in for POM the movie was the same toys the POM cartoon series tie in released 4 years prior. Something I've never seen before. They really didn't want Home to fail, so they just said "screw it" and threw POM under a bus.
