Movie sequels aren’t always the big splash their creators want them to be. Fans of a surprise-hit original are often disappointed on the second go-round. But Finding Dory might just surprise some critics. This fish-in-and-out of water tale doesn’t try to match stroke-for-stroke with Finding Nemo when it comes to story-surprise freshness. There’s no bad-fish smell here, but the slapstick adventure feels simple, comfortable and smilingly predictable. Where the film really swims like a champ is when it comes to the beating heart of things.
