Starting from the bottom, the story was not really there
Of course, there was a story; Riko found out Natsuo's secret, and is coerced into teaching her about love, and then more characters join, and there's a few bumps along the road... But it's a very bland story, very generic story, and without context, a very boring story.
However, the characters play into the story's stronger points, whilst overshadowing it when it's weak. So whilst there's a story there, it is more of a guideline, than a story.
Generic sound... again
After Hibike! Euphonium, I think it's going to be hard to give more than a 6 for any anime which doesn't do anything special with its sound.
Although Love Lab had a great OP, and some very good whacking sound effects. Beyond that, there's nothing to note, although that's to be expected of this type of anime.
Finally onto the good stuff!
The artwork for Love Lab was great quality for its genre. Although it's still very generic, it is a lot crisper, and with some very well done special effects. There's nothing overly complex with the art in Love Lab, but it's just the right amount of everything, without going overboard, and without having certain aspects look off.
The characters though are what you will be watching Love Lab for. The dynamic between the characters is very well done, with each character having very defined traits, whilst also not being confined to them. For example, Enomoto, who is a very obvious tsundere is portrayed as such for the most part, but we still see traits of her which develop her as more than just the generic tsundere character.
As a whole, everything about the anime ties together quite neatly. Though there's things I would change, it was still very enjoyable to watch.
Aaaaand that's it for this review. I started watching Mahou Shoujo Madoka Magica this morning, so that will be next to appear here. I can already tell that's going to be an interesting one to review, and I'm really enjoying that so far. But that's another review for another day, so until then じゃね!
