My biggest pet peeve with comedy anime, which is especially prevalent in moe comedy anime it seems, is when emotional tension is undermined by poorly placed gags or jokes. Sure, I'm watching the show because it's funny, but if a show was ONLY funny and nothing else it wouldn't be interesting. This is something that love lab does extremely well. It's not the funniest show I've ever seen, though it did make me laugh a decent amount. What I love about this show is the combination of comedy and drama, which synthesize together to create the ultimate wholeome and heartwarming anime.
I was positively surprised by the amount (which is not a lot) of romance in this show as well. While it is titled "love lab," that mostly pertains to the activities (fantasizing and experimenting with romance) of the student council of an all-girls school, whose 5 members are the main cast of the show. I didn't watch this for the romance aspect, and I advise you to not expect too much romance either. The "romance" (if you can call it that) that is in this anime is extremely minimal but pretty wholesome. There's no relationships or anything of the sort, but the boys that are included I don't dislike.
One big part of this show that impressed me was the animation. Honestly, in some episodes, this anime felt more like a Kyoto animation production than a random anime studio. That's not to say that the animation is as good as Kyoto's, because it's not, but the fluidity with which characters move is rather impressive.
I've actually noticed that with other anime by this studio (doga kobo) as well, such as plastic memories, sleepy princess, and especially (the exceptionally well done and highly recommended) My Senpai is Annoying, which is very wholesome and has exceptional animation. Other very good shows from this studio, (I love and would recommend all of them) include New Game, Yuru Yuri, Gabriel Dropout, Himouto! Umaru-chan, and Asteroid in love. This is not everything famous by them, but these are the shows I love the most. (Doga kobo rant over)
Overall, This show is criminally underrated, and I would strongly urge you to give it a try.
