In all fairness I haven't been to any other outdoor cinemas so I don't have much to compare this to. I don't think they are really doing much wrong, but for me it's just not the best experience I've ever had. I've been four times, all of them cold nights with three of them REALLY cold and even rainy. I'm talking bust the winter gear out of storage cold.
Last night it was slightly warmer and REALLY packed. We saw Argo (which was amazing by the way) and unfortunatley due to the popular demand, they sold out of the back rest chairs 40 minutes before the movie started.
The last two times I've been I felt the sound wasn't loud enough. A friend and I were saying how we both feel we need to watch Argo again because we missed a lot of the dialouge. Also, because it was so quiet at times, the fans that blow air into the screen were actually louder than the movie, impairing our ability to hear. The food stand staff yapping right behind us didn't help matters.
On the topic of food, while it is overpriced (that's a given at any cinema) I like the fact that you can order Crust pizza and overall it's not any pricier than any other cinema. I still recommend just bringing your own food. It's cheaper and more enjoyable.
With all that said, they do have a good selection of movies each year and if you go on a nice evening and have a picnic, I'm sure you'll have a lovely time. Make a night of it. Don't just go for the movie (like I did the last two times) or you will surely be dissapointed. To me it's just a more expensive, less comfortable way of watching a film and the picnic is the only thing that makes is special. Just don't forget your jackets, even if you think you won't need them. read more
