Regardless of whether you like or dislike Abba, it is a hugely entertaining show imo, you just can't help but come out of the theatre on a high, it is as others have said, a feel good type of show. As to how well its has transferred at the Novello, the set is quite basic, so not an issue. Seen it twice there and would happily see it again. Packed audiences both times and people on their feet dancing at the end. They can't all be wrong. Get and see it would be my call.
In reply to Jordosaur, the view from those seats is good although regardless of where you seat it all depends on who you have sat in front of you! Personally I'd pick seats around the premium ones or just behind, in front is too close! I may have two tickets available for the Thursday 15th performance in the Stalls, row H next to the premiums, part of a group booking where two haven't yet paid, should know on Monday. If interested, PM me, will do them for £65 the pair.
