Okay where do I start?
Overall, the experience is decent. They have only 4 theater screens which makes sense because Grenada is a small town. Two out of the 4 are the smallest, with a long narrow room with a screen at the end. There is only one walkway with I think 3 or 4 rows of seats on either side down the length of the theater. These two are probably where most of the complaints come from. There are two really decent quality theaters that are about the normal size of any normal theater you go into with one being capable of playing 3D movies. They usually play the newest movies that release, or the ones with the better ratings on those two theaters.
The seats are hit or miss. Sometimes you may get a really crappy seat that you have to support most of your weight down on your legs to keep from sliding out. Others are just fine and the seats are for the most part comfortable. They allow some flexibility to recline back a bit to make it more comfortable.
I am used to going to a theater where you could pay upwards to 10 dollars just for a large bucket of popcorn. Here, I bought me and my dad a large drink and popcorn each for 10 dollars. Yeah, I get that the sizes are actually considered medium in other theaters, but food is food and you don't go to a theater to eat food. You go to watch a movie and maybe have something to snack on. Same with the large drinks. The cups are probably considered medium everywhere else, but I haven't had a problem with it. I pay a cheaper price for the food and enjoy the movie. Then I still have money to go eat out somewhere when I am done. I give it a 3 star because it is a decent, solid movie theater with just a few mishaps and hit or misses. Other than that, just enjoy the movie you want to watch. The sound and screens I've seen have been good so far.
If you're just passing through, I'd say you may be better off waiting until you get to the next town. But if you have to stay a weekend or what not, then it's really no major inconvenience especially if you're looking for something to do while you're here.
