Finding Dory rests on the slippery scales of the befuddled blue heroine voiced by Ellen DeGeneres. It approaches the heights of Finding Nemo, thanks to the filmmakers’ embrace of the darkness, dread and possibility of failure Dory faces.

If Finding Dory is guilty of anything, it’s the sin of familiarity. Just as J.J. Abrams buttressed the story of Star Wars: The Force Awakens to the structure of Star Wars: A New Hope, this sequel feels like a carbon copy of 2003’s Finding Nemo — complete with a long distance quest, a family divided and the hero trapped, but trying to escape.

Both the charm and challenges of the new film rest on the slippery scales of the befuddled blue heroine Dory. Ellen DeGeneres returns as the voice of the scatterbrained Paracanthurus, who is forced to live in the present because she forgets nearly everything else.

“My name is Dory and I suffer from short-term memory loss,” squeaks a toddler-aged Dory in the film’s opening moments. Straight away, we meet her parents (voiced warmly by Canadian comedian and actor Eugene Levy, and Diane Keaton), who are worried about the fate of their little girl. So far Finding Dory has earned 4 out of 5 starts and lets hope for most powerful result as it is expected to be the biggest blockbuster of the year.
