Like the title says.

It was harmless fluff.  Not bad but certainly not good either.

The couples were cute, but mostly it was stereotypes of old people.

• Storytelling – C – I did finish.
• Voice – C – I guess most anime don’t even try to depict old people (by which I mean of course over 18). Didn’t really succeed but eh.
• Characters – B – Stronger part of the show. Titular grandma and grandpa were boring however.
• Attention Grab – B – I was honestly surprised this managed to remain engaging.
• Production – C – Looks fine.
• Overall – C

Recommendations – Hang out with some elderly people
