Oh gee, hardly a statement I could agree with.
Out of all the episodes, lbt 9 was the worst in my opinion.
In my opinion LBT 9 was one of the best sequels produced by Charles Grossvenor (rivaled only by LBT 5) and the definitely the best one we have seen in recent times.
It was a great story though.
In my opinion it was not the story which made LBT 9 great though. The story is basically as simple as a story can get. Somebody far from home fiends friends who bring him back in spite of the hardships and dangers of the journey. To make it a bit more of a plot there is a bit of conflict within the group (mainly Cera vs. Mo) and some subplot elements like being bored for being alone. There is nothing nearly as complex in the plot of LBT 9 as in almost every single other Grossvenor LBT movie.
The new computer graphics used were beyond terrible and they didn't match anything around them.
Yet another point I have to disagree with. While there were some examples of poor graphics in LBT 9 (the log you mentioned) the overall work with computer graphics was much better than in any previous LBT movies and there were no blunders as bad as some cases from the later movies. The first 3D animation we ever saw in LBT was in the prologue of LBT 7 and it just didn't fit in with the rest of the animation at all. The same goes for many 3D animations in LBT 10 (e.g. when Littlefoot is climbing up the tree). There is nothing nearly as bad in LBT 9. They made a much better job in blending photo realistic skies with the rest of the landscapes (no more dark green skies such as those we had in LBT 8) and the water too, in spite of being photorealistic, fit in quite well. Light reflections on the water surface etc. came across quite nice. The thunderstorm during which the final fight with the swimming sharptooth takes place is another example of very good animation work in LBT 9.
Mr. Grossvenor also didn't use strange color effects in LBT 9. I already mentioned the skies, but it should also be noted that for once everything and everyone didn't turn red in case of danger (one of the Grossvenor effects which seems to be really silly to me). As if to compensate for that Mo is about as shrill colored as shrill colored can be. When I first saw the cover of LBT 9 before the release of the movie I was horrified. "Pokemon invasion to LBT!" was my first though. I was surprised when I watched the movie and didn't feel bothered by his shrill colors at all (maybe Chomper had done his job to accustom me to strange colored dinosaurs).
There are also many inconsistancies in this sequal. I counted 68 inconsistancies and errors.
The major inconsistancy in my opinion was the use of that little landbreak as a barrier preventing Littlefoot and the others from getting home. Sure enough Petrie should have been able to fly across at a higher altitude and if they have a flyer who can carry Littlefoot, Cera, and Spike down from Threehorn peak (something so unrealistic that I consider it an inconsistancy of LBT 7 rather than one of LBT 9) there is no reason why that flyer shouldn't get them across that little landbreak. It might have been better to develope a plot without that earthquake supposedly forcing Littlefoot and the others to bring Mo home (no doubt there was no need for them to go all the way to the big water in order to get home again). There are much worse blunders in other LBT movies tearing the consistency not just of the respective movie, but also of earlier movies apart (LBT 10 being the worst example). Some of the blunders of LBT 9 have been there before, so if we were willing to take them back then, why would it be impossible to accept them now (e.g. Petrie could have flown over the Big Water in LBT 5 but he didn't for pretty much the same reasons for which he was unable to fly accross the landbreak in LBT 9).
Also, in about 15% of the film, the characters looked out of proportion.
There are scenes with characters looking out of proportion in every single movie. If there are so many cases as you claim (15%) you can undoubtedly provide many screenshots of the respective scenes, can't you?
