This is going to come down to your personal taste, for sure. You got unlucky that nothing already on your plan to watch list was at 7 or below! I had a bunch. I totally ignore the community rating when I add things to my list.
So I'd say, just find something you think sounds interesting, but has a lower rating. It may work for you. Checking older shows might get you somewhere as well. Ratings for things 5+ years old are way less inflated to begin with than newer things. Or find a lower rated work of an actor or actress you already like that you think might help drag you through if you end up not entirely loving the story, lol.
Quick recs, though:
Shikaotoko Aoniyoshi (6.8) - weird, but entertaining, also pretty short
Attic Cat (6.8) - one of the "old" ones, I remember it being pretty entertaining, but it is a bit dated
The Musical (6.5) - yes, the romance in this one is awkward as hell. The overall story is not bad, though.
Someday (6.9) - Starts great, then opinions get mixed. Still, great cast and really innovative for its time.
Freeze (6.3) - Odd ending, RIYL vampire stories though. Really short, so it has that going for it.
