I bought a FireStick at Bestbuy a few months ago and installed Kodi myself in 20 minutes. Don't overpay someone to install it for you. The stick is $40 at most places. As far as streaming live channels, the best addon is Phoenix and it's still pretty poor.
As you mentioned, YES, you will find movies that are currently in the theater but the quality will be very poor (usually a guy with a camcorder pointed at the theater screen). The same applies to Live TV. I tried to stream CNN and ESPN and they were basically unwatchable.
So, for movies that are out on DVD, you will probably enjoy Kodi. But for live TV and really new movies...it isn't nearly up to par. For now I have Kodi, Netflix, and Directv.
