The most frequent excuse I hear is related to the age difference - this usually comes from people who'll then proceed to watch any number of Ecchi Harem stacked to the rafters with Lolis. The main female character is 17, which means she's of legal age of consent in most western countries. I'm sure you'll all be horrified to hear that 17 year old's do sometime fantasize about older adults...clutch those pearls!
Now that the arbitrary excuse for not watch it has been dealt with I'd like to make to case for this anime. I've found it to be one of the most engaging series this season. It's at time funny, dramatic, heartwarming and treats its subject matter very seriously.
If you have your doubts please watch up to, and including, episode 7. I promise you that you will not be disappointed. there is something very poignant about the contrast between an adult who's dreams have been crush by the passage of time but who, nonetheless, remains kindhearted, running headlong into the intense passions of a young adult experiencing her first love in the face of a life changing event.
