I hate them. They're awful. I mean, really. How many Land Before Times are necessary before they get the idea that we, the public, are over it? I have always avoided sequels to decent shows, when it's obvious that they were only done for money.
Unfortunately, I know have a two-year-old, who adores a large green ogre named Shrek. And after the first two-hundred times of watching the original, I gave in and watched part two (which Stacey owns). Which Miles promptly fell in love with. And watched a few hundred times.
There comes a point in every person's life when reality wins out over ideals. Watching an ogre meet his in-laws for the thousandth time was mine. I caved, and asked for parts three and four for Miles for Christmas. Now, when he wants 'Feck, I can at least cycle through four different movies, so that I'm not reciting every line word for word in my sleep. I still hate franchises. But, I understand them, now. And I endorse them with my dollars.
But once my son is past this stage of life, I plan to go back to boycotting them again.
