Crest Plz 

Meh, the first was really smooth, but the second and third (and kinda the forth) was a joke for the movement.
Don't even get me started on the polygons on the third of the mountains.

Though, I don't want to spread hatred here either. I actually did like the third movie despite choppy animation and bad land graphics. Hehe but I would rather not spread negativity either. (Suggestion to anyone, even my self)

However, I hope the sixth sequel will be like the first movie.

I don't think any of the sequels wilkl be like the first movie. And I don't really care about those flaws
I still like the movie

i don't like the third movie that much anymore, but now it's a guilty pleasure for me. yea, it's definitely the worst of the franchise, but i still find some enjoyment in it (even if i give it a 4/10 score now)

I would like to suggest: There is nothing guilty for liking something some other people think is terrible. :) - In case you think it that way.
If you still personality find it guilty, it's alright then. XD

On an extra note:
The third one had so many bad graphics, lack of plot, and choppy animation. But it does offer more of personality than a lot of the sequels though IMO which was why I liked it a lot.
