I didn't think it was too bad when I used it recently - certainly compared to T1.
I found a member of airline staff having a coffee and quizzed them on T2. Apparently some of the upstairs (premium?) food outlets won't open until the terminal gets busier. The old gates (which I also used) are only reached by stairs and rear of security path until a second phase of T2 refurb starts up.
I thought the views onto the airfield were really good and apparently - not that I used it - the premium lounge is really good.
Not comparable to MUC, but I'm not sure it's fair to expect it to be.
