Secret Life of Pets
Animation over the last 25 years or so (beginning with Little Mermaid and continuing on through Lion King, Shrek, Toy Story, Finding Nemo, etc.) has really raised the bar. Some of those films are as good or better than anything I've ever seen. Lion King, for instance, is a masterpiece in nearly every respect. Visually stunning, intriguing story, fantastic music, amazing voice actors and full of lessons on the nature of life, love, jealousy and greed. Just a magnificent movie.
This one? It might have seen the bar but it never got near it.
The animation was okay, the voices were ehhhh, and the story was flat. For animated films to work they have to do at least some of the following well: Be visually captivating, have strong characters (which require strong character voices), have some inappropriate material that adults find funny but kids aren't sure what they're laughing at or tell a good story. This did none of those things.
I'm not sure kids will even find anything to keep their attention during this movie. It had no shine.
