Yeah, I don't think reviews are going to have much weight here. Illumination is no stranger to making a solid profit from their budgets, and more importantly...
...theaters haven't had a notable G/PG film since Puss in Boots: The Last Wish, which came out last year. And there's no direct competition on the horizon for a while, either. That is the making of doing just fine at the box office as you're the only game in town.
