WARNING: I have not watched everything as I am kinda just in a hurry. So it's quite possible this review is generally biased atm.

But for now I'll just post some quick thoughts.
The Animation is the worst thing I've ever seen in all of the series: The movement is choppy, and very repeating in some parts. The part where the wolf howled just showed how lazy they have became.

Now the whole movie so far feels like a misleading title.

The only parts I've seen that were good was the creativity (I don't think calling it a rip-off would be fair as that's like calling every movie a rip-off), and the dancing and the joy Humphrey has (I could be wrong as I didn't watch it), the new unique designs of the bears, and some interesting music.

As much as I defend direct creativity (ideas alone and Wird angezeigt ideas), it still doesn't change that there is lack of effort such as choppy animation, bad lighting, low-polygon Models a lot, and other legit lazy things.
Yet, even though it's an effort alone, why make a movie about anthropomorphic Wölfe when half of it isn't about anthropomorphic wolves? The only time I would call out an effort is if it makes the whole effort (e.g. title) bad and this is one of them.

Of course, I am not a bad critic who stifles creativity and likes to be an asshole to the creator (I want to be a sane fan), and if they wanted to make a Pixar quality film with only the Welpen growing up, I can't call it out even if I hate it, I still want to say that the movie has a lot of problems.

Pros:
Creativity
Music
Anthropomorphic personality adding personality to the characters.
May be enjoyable to kids

Cons:
Bad animation; choppy and it repeats a lot.
Misleading movie title.
Nintendo 64 Models.
Bad lighting.
Welpen still looking like Welpen within a universe where the Wölfe do grow in months.

Remember, this review is based off what I've seen so far.

Tom Kane, I respect your attempt at making what Du want in a fictional film, but I hope Du also improve if Du plan on making anything in the future with Alpha and Omega.
