Broken Base: The movie, which has a villain that tried to and succeeded in taking Clifford away from Emily Elizabeth, and an large heaping dose of Mood Whiplash thanks to Jody Gray's contribution that is an extremely depressing soundtrack. Part of the fanbase loved the emotional roller coaster. Part of the fanbase (which wanted a happy romp around Birdwell Island and nothing more) thinks it sucked because of being put through emotional roller coaster.
Tear Jerker: "Friends Forever", where a young T-Bone has to deal with the fact that his friend, Hamburger, is moving away. Their goodbye is sad enough as is, even if you didn't grow up watching their voiceactors.
Uncanny Valley: Everyone in the movie has normal eyes. Some find it well suited, given that Clifford was the only one withoutBlack Bead Eyes. Others find it a bit creepy.
