After a Question is raised anybody is bound to think about it.
Now I tried to analyze myself.
Did I like Narnia? Yes, of course.
I liked Narnia, I've enjoyed the first two movies, but I didn't bother to go to the theatre and watch any of them. I've enjoyed them when they were aired on TV, but Harry Potter drags me to the theatre.
What other movies did I like?
There are many I might have enjoyed watching. Today everyday, while surfing the TV Channels, you are bound to watch some movie or the other, and you might like a few.
I liked Princess Diaries, I liked Alice in the wonderland, I've enjoyed watching Narnia and High School Musical and perhaps many more, each for a different reason.
Why can't we like a certain movie?
I confess, I didn't enjoy Lord of the Rings. But nobody can exclaim and question "How come you didn't enjoy 'Lord of the Rings'?" May be I can't explain but I just didn't like it.
Liking or enjoying or just watching or reading or not liking a movie or a novel or a TV program can't be explained everytime and I think need not be either.
So to the Twitter Question "Narnia/Harry Potter?" My vote is to Harry Potter.
