Time and Time Again can pretty much be summed up as a typical isekai. There are fun moments and fun characters, not to mention this would probably transition well into a 12/13 episode anime. But if you're looking for the next Re:Zero or Eminence in shadow, you might feel a bit underwhelmed. While this story does have some Re:Zero elements, it feels more like something in the vain of Summoned to Another World... Again? or Groundhog Day in the sense that it contains a character who's "seen it all before and knows how to handle things". Nothing wrong with this approach, but there are times I wish I could've seen more of the struggle of the characters, the "failed runs" so to say instead of the perfect run. Still, it makes for a solid isekai.
