Personally, I don't care about any of the pairing possibilities. Initially, the love-triangle came on as forced to me. I understood Sheryl's interest in Alto (he didn't fawn over her like every other guy did) and I understood Ranka's interest. However, Alto never really grabbed me as the lead character and so while I initially liked Ranka more than Sheryl, I didn't ultimately care whom he ended up with. After all, the writers keep tossing things back and forth in an attempt to make Ranka the liked one, then Sheryl the liked one.
This anime has too many cliches for my tastes. Plus, it seems like they are trying to give noRAB to every previous Macross incarnation (which I understand) but in doing so, at times I feel it is a burden on the series.
Anyway, my own episode review (with more bloviating).
