Only for fans of Asemu Arc from the original show. The first episode of the OVA isn't so bad (feels like a retelling almost), but the second episode carried expectations that Zehearts character would be expanded upon beyond the unsatisfactory development he had in the original show. That is unfortunately not the case, as they simple double down by showing more scenes that affirm that he is a stupid character, and basically ignore the actual plot ofnl the show to just show him moping on the mothership. I can't recommend this to people who haven't seen AGE, as it (especially in episode 2) expects you tofill in missing pieces with knowledge of the actual show. It also is FIRMLY Zehearts perspective, but despite that sounding like a good thing on paper, they don't actually add anything to his characterization. The OVA does have some nice newly interpreted fights from the show that fans can look forward to, though.
I would have been really happy if they focused more on Rosamys role in the story of Xeheart and Asemu, they could have fixed a lot that was wrong with those two characters roles in part 3 of AGE if they had done that. Unfortunate. At least episode 1 is "fun". (As a side note, Kio and Flit barely even cameo in this version of the show)
Unlike the great Wing OVA "Endless Waltz", this can only be recommended to Gundam AGE diehard fans.
