I don't have enough good things to say about the Spectrum. It is truly a treasure to the Capital Region.
Although they are not the biggest theater in the area, they have the best quality of films. You will not find much fodder here. Their shows are normally very popular movies or more obscure ones that you are not able to see at the Crossgates theater. Spectrum was showing Brokeback Mountain when none of the other theaters in the area were. In fact, it was the only theater in the Hudson Valley which offered it, the next closest theater being the Palisades Mall.
Another great thing about Spectrum is their concession stand. It has reasonable prices in addition to a selection that is much better than your normal theater. They have REAL buttered popcorn, home made baked good, and ice cream.
Additionally, their ticket prices are good too. I believe it is about $8 for a weekend showing. They have Tuesday matinées as well at night which are $6.00.
