I hope your church won't ban Macross. That would quite a tough decision for you.
BTW, you didn't lose much for not wathcing HP4.
It sucks. That's how to destory a good story, gutted out all the interesting parts, kill the suspence plots, and leave only the mindless action scenes. The HP4 book is one of the best, it's on-par with HP3. But this is the worst HP movie.
I doubt any church dare to ban LoTR or the up coming Navarra movie,
although they all contain pretty much the same kind of magical stuffs.
The only difference between them is J.K.K.Tolkien and C.S.Lewis are well known christian writers, where J.K.Rowling is just a nobody (or was a nobody a few years ago)
If J.K.Rowling suddenly declare herself believe in God tomorrow, all the church critism on HP will disappear at once.
