I'm starting to think that ignorance is bliss
In some ways it is. Your first mistake was posting here in the midst of a bunch of audioholics.
The difference in sound for movie watching can't be that much can it???
In the end that is a question only you can answer for yourself. When I picked up my system, it was to be music first. I figured I could be happy with the sound from my display for movies. Now that I am actually sitting in my livingroom enjoying better-than-theater sound for everything I watch, I can't see ever going back to anything lesser.
The other way to look at it is that if you pick up the energy's now and are not satisfied, you can always sell them and pick up something better. Consider the small loss you take on selling the system as the cost of learning.
Either way, get 'unstuck' from the analysis and start enjoying something. You will be glad you moved forward.
