It's that movie's fault DreamWorks Animation had to write down
Mr. Peabody & Sherman, and it pains me greatly that it was actually good.
Also, it's a Warner Bros. animation project that doesn't acknowledge anything else they own apart from the DC characters.

It's true. Both The Iron Giant and Scott Pilgrim bombed, and both were up against films that went on to be huge box office successes -- Giant with The Sixth Sense, Pilgrim with The Expendables.
I don't hate The Expendables or The Sixth Sense because of that, though. They're just movies, and while it is disappointing to see something you enjoy be considered a flop in terms of money, that can't stop you from enjoying the film itself. (Hell, perennial Tre favorite Turbo opened a few weeks after Despicable Me 2, and while I didn't like that one very much, it was more because of the film itself than anything else.)
I think it's also important to note that both Turbo and MPAS got the Netflix treatment (with multiple seasons!), something that probably wouldn't have come about at all if DWA had no faith in the franchises. (Granted, they have a bunch of TV stuff these days, but both of those actually appear to capture what made the films enjoyable on a smaller scale, something that can't be said about all of their spinoffs).
