I'm an Unlimited card holder and go to this cinema at least once a week (on Orange wednesdays) if not more, depending on the films showing.
I think this is an excellent cinema, rivalling the Vue at Westfields. Most of the screens are very good quality, a couple of the smaller ones (e.g screen 11) feel like they haven't been kitted out with the same system as the others, so can feel a bit old-school audio quality when compared to screens 1, 3 or 6 for example.
I have had a couple of minor issues (curtain not opening fully, forgetting to dim the lights), but on these occasions I just nip outside quickly, tell any passing staff member and they've been sorted quickly.
The seats are comfortable and able to ward off bum-numbness for even the longest, most dragging of films (*cough*lord of the rings 3*cough*), however the seat arms are quite raw on the arm after a while. I'm beginning to form a cunning plan to wrap my arms in bubble wrap under my sleeves before going to a movie to give me both arm-based comfort during the film and pop-tastic entertainment during the boring ads.
Don't worry about the review below me - I've never had an issue with ripped/scratched screens, and I go very regularly. Plus, if you do have any issues just complain to a manager and they'll give you free tickets.
