My First Assumption...
when I read the plot line was that it was going to be similar to "Pillow Talk" but instead of sharing a phone line, they're sending pen pal letters. I told myself, though, since I like "Pillow Talk", I'll like this movie.
Well, I was right about liking the movie, wrong about it being similar to "Pillow Talk". I'm glad I watched this film...it was great!
That's my opinion and I'm sticking with it.
