The seiyuu offer a good, consistent performance, so no complaints on that front. The ending theme songs, however, are rather at odds with the general tone of the series. The first ED passably complemented the series, but the second one was too upbeat. Don't skip out when the credits roll in the later episodes like I did at first, though, as it comprises absolutely gorgeous artwork.
Maria-sama ga Miteru OVA also explores different relationships that weren't previously addressed, in addition to delving into existing ones at greater length. A few characters that we haven't seen in a while are brought back (some only momentarily) and there's at least one character introduced that we haven't met properly yet.
For some reason, in the OVAs they've stopped the tradition of using tongue-in-cheek humour for the episode previews, and it's vaguely disappointing in that regard. (The DVD specials are as funny as ever though, but that's another kettle of fish.)
There were some cheesy-- but heartwarming-- moments, and it's getting increasingly to the point where the f/f subtext can't be called subtext anymore. To be sure, little is of the "in your face" sort. Some appreciate such things expressed forthright, but it is not in line with Maria-sama ga Miteru OVA's style.
So in that sense this series might not be such a good choice for these people, but I think after watching the first and second seasons, we should all know what to expect. If you haven't started liking Maria-sama ga Miteru as a whole after two seasons, it's unlikely to change in the third. With that in mind, I can only say that Maria-sama ga Miteru OVA was above and beyond what I expected.
