Love Lab is pretty average in terms of characters and production values, but it is quite a cute show. This will just be a brief review.
Brief Summary: At an all girls' school, Maki, the student council president, is secretly interested in how to attract a boyfriend. Riko discovers this secret, and is forced to join the student council because of a misunderstanding: Maki thinks Riko is a "love expert."
Story: The story itself isn't anything new or unusual, but the misunderstanding about Riko's "love expertise" persists until it becomes a roadblock for the characters' relationships with each other. The final episode is spent resolving the misunderstanding, which drives the drama of the characters interacting with each other.
Animation, Sound, Characters: All of these are pretty average, bordering on boring. The characters aren't too bad, but they're not super nuanced either.
Overall: If you like cute stories about friendship, this one is pretty damn good, despite its plain packaging. Cutely comedic, fairly innocent, and definitely dramatic.
