I actually just thought of a single complaint about the BTWB in Dublin
I think because she only did 1 date in Ireland, she felt the need to cram as much into one concert as possible. Because of that, many songs she only sang verse-chorus-bridge-chorus, rather than including the second verse. This particularly irritated me with MTN

I kinda wish she had cut a couple of songs (LoveGame, for example, didn't do all that much) or at least some of the talking

Apart from that, everything else was perfect
