Saekano, the show that keeps on giving regardless how fan-servicy it can be. As a special episode that premieres before the main series' debut, expectations coming into this was more for popcorn entertainment value than anything else. Let's face it, even the title (Fan Service of Love and Pure Heart) of the special implies fan service and really, you'll get it right at your face.
The first few minutes of this episode has some of the most suggestive camera angles in the franchise. It invites attention with the main heroines in skimpy swimsuits. There's actually a reason for this as Blessing Software is looking for new ideas for their project. Megumi is still the centerpiece of their work and so as a way to make her feel "comfortable", everyone decided to go to the pool as a more fitting setting. Tomoya also ends up there where he seems to be trying to rid of his earthly desires.
Romance rivalries is still pretty evident. Two of the main girls make moves to get Tomoya's attention. In fact, Utaha makes a bold move to manipulate events as part of an elaborate plan to spend alone time with Tomoya. Michiru still displays her tomboyish personality while not being afraid to use her sporty body as an advantage. That leaves Eriri where she's more of an oddball in this rivalry. She's still the same Eriri we come to know yet she isn't as bold as the other girls. There's probably a reason for that as she has an inferiority complex about her body. The main title of the series, 'Saekano Flat' might even be a reference for this. Finally, we also get a familiar reappearance of Izumi as she returns to thank everyone.
Beyond the fan service, the episode itself serves as a reminder that Saekano is still about game making. Blessing Software still work as a group regardless how silly their methods are. Tomoya is caught in the middle while Megumi fills the role of the ordinary protagonist. The fan service serves more as a way to give fans a treat as all the girls looks fairly nice in their swimsuits. However, this special isn't and shouldn't be used as a way to give audience an impression about the entire second season. It merely serves as a way to get viewers back into the franchise. It's been over two years since the debut of the first season after all.
