The Brewery could've been lovely, I'm sure. However, it really is just a place to go to see a film at the Cineworld cinema there (or the slightly more upmarket Screening Rooms if you're that sort of person).
All the restaurants are boring chains (Frankie and Benny's, Harvester etc) and all the shops have shut. The site is located behind the Lower High Street and that is hardly a selling point. It's a shame they didn't make more of the approach.
