As with the first season, Sailor Moon's biggest weakness is its plot. Less intriguing than the first season's but just as formulaic. However, despite the overall plot lacking much interest, it is still a joy to watch every episode due to the amazing characters and their emotional journeys. Usagi and Mamoru's relationship was simply a low point, however. The finale was specatcular, approaching some more mature themes than the first season did.
The animation is pretty much the same as in season one - very gorgeous backgrounds, intriguing villain designs, and minimal movement for minor scenes. There are less stutter shots in this season, which I consider a plus since I don't like them. The costume design this season was particularly amazing because of its alien characters, who wear more baffling styles but make it work.
The sound is also similar to the first season's. Repetitive, but effective. A lot of the score is simply the same as the previous season, but the new songs were very good, especially the new transformation music and the ending songs.
The characters continue to be the strongest aspect of Sailor Moon. This season, Usagi's character grew infinitely more appealing as she matures, becoming my favorite character this season. Minako also gets a lot more character growth, which she didn't really have time for in the first season, coming in very few episodes before the end. Rei got less focus this season, but was fantastic every time she was on-screen as usual. Chibi-Usa is very annoying in the beginning, but I don't hate her by the end, so there's that... Makoto is alright this season, but her character is rather weak to me and has been since the beginning. Ami this season, however, was downright boring - her literal only personality trait is being smart and studious, and she cares for nothing else (apart from friendship, sometimes). Sailor Pluto makes brief appearances this season and she's quite mysterious, but nothing more than a minor character. The villains were all very intriguing; some of them received quite good redemption arcs while others were written as well-rounded antagonists, with reason behind their actions yet not justifying their evil deeds.
Overall, it was on par with the first season and very enjoyable. The romance takes a dip this season when it was already not a high point in the first, but it's a very minor aspect in the grand scheme of things. As always, friendship is much more important to Sailor Moon than anything, so its major strengths lie in the group of girls.
