What do you think of Rear Window?

I watched it today and I found it so boring and passive. I get that many people like this movie, but it didn't work for me.
After having watched and loved Psycho yesterday, I came to this one with some expectations that were frustrated. I thought some stuff was kinda dumb and too simple, especially the ending. I guess I prefer more direct, psychological, and a bit dark thrillers - I don't like movies that are "too dark", but I thought Rear Window was too colorful and tried to be a little too light and funny for my taste, lol.

What do you guys think of this movie?
