Clearly, it takes a lot of time to design and animate those little snap-on sets, so we can't give Warner Bros. too much grief for taking its time. Seeing as how Legos have been popular since our parents were kids, we're sure they'll still be all the rage in 2017. Besides, we waited nine freaking years for that Before Sunrise follow-up and that all worked out okay.
The hard part will be breaking the news to the little ones. Three years is (literally) a lifetime in toddler years. Expect some major tantrums and tear-shedding, and pray that those Frozen 2 rumors turn out to be true. (Vulture)
