The movie is underrated.
I think it deserves more of a share from several companies.

The main reason some people hate it is because some people were expecting something more different than other films involving the plot, though is it really fair to compare it to other films to judge the quality?
Some suggest kids don't count I think but for something like this, that is very untrue because it seems so odd to say it's "bad" because 'adults seen it before', it's basically nostalgia reasoning. So because of that, it's fair to say the movie is 'good' for kids if that was the main reason why some people vote it down.
Besides, it's still creative in the end as I never seen anthropomorphic wolves do this and yet, the plot isn't exactly the same.

Plus, the characters are likable (Humphrey, Kate, Lilly, and Garth) by a lot of people, and they all look so nice and memorable. It sucks some people tend to forget that when rating, and possibly worse: suggest that they must look like boring generic realism wolves to be "better". That's not fair.
And like, try to imagine all four main characters having the same exact anatomy (Companies change anatomy to help unique looks I think?) and no human-like hair.
-Edit, I aplogize, the link doesn't work, it was a picture of four wolves. Edit Completed-
(Colors are more different in this picture though)

I always hoped the critics didn't damage the reputation of the movie with possibilities that many more unknown people would of liked it. I would barely worry if some people didn't treat critics as "right" and use that as "reasoning".

your right

its my favorites movie of all time

:D
