Only thing that irks me ever so slightly is when a decent sized PV (i.e. Bokura no LIVE kimito no LIFE) is immediately followed by the ED. It'd make more sense to finish with the PV, but that's just my opinion
Nearly brought a tear to my eye with the PV - bizarrely felt quite nostalgic, seeing as how this song was how it all started.
Loving this series, has always had that down to earth feel.
