BELIEVE IN MIRACLES
Miracle Girls is a Slice of Life/Magical Girl anime that ran for 51 episodes during 1993. In a sentence: The Matsunaga sisters, Tomomi (short hair) and Mikage (long hair), are a pair of twins who have the powers of telepathy and teleportation, and the series follows them and their boyfriends as they go through daily life in high school and get into misadventures. This series is interesting historically because the Slice of Life side is far more prominent than the Magical Girl side and the series therefore reflects the origins of the Magical Girl genre moreso than the modern, Sailor Moon-esque Magical Girl shows. (Sailor Moon itself had existed near the same time and had ended up winning in terms of how many series it influenced down the line.)
A strength of Miracle Girls is the characterisation---plenty of interpersonal conflict to go around, especially to and from Mikage---and the occasional multi-episode arcs are where the characters are at their best. I liked the way that Ema and Marie parallel Tomomi and Mikage, especially with Marie being presented as initially selfish but with a good nature beneath. Despite the relatively small amount of screen time she got, Marie got good character development. I would say that the sitcom-esque plots of many of the episodes are the weakest point. Something arbitrary and usually magical tends to happen to set events in motion (for example, the dinosaur episode), but you know that the status quo will be reasserted in the end, so that takes away from the emotional investment. It's best to think of the plots as just setting the stage for enjoyable character moments to occur.
Where this series really shines, though, is in presenting a sincere and warm view of relationships and young love. Tomomi and Mikage take their relationships with their boyfriends seriously, staying with them throughout the whole series. It makes the series feel like a relic of a time when there was more optimism about young peoples' prospects for relationships and love, and that this optimism permeated the stories that people told. The music is pretty great too.

Some private tracker sites have an alternate available (BBT-RMX) with slightly better video quality, but the subtitles in the alternative are broken in a few of the episodes.
