This show is unintentionally funny on a regular basis, but also walks a line where it's quality of writing, acting, camera and lighting work, soundtrack etc are often pretty well done relative to the resources available to the crew. If you expect it to be immaculate you won't have fun, but if you can take it with a grain of salt this show is incredibly entertaining.
If you like rap music and/or are from the detroit metro area, you might hear a lot of familiar songs being featured as well. I especially like vezzo and 42 dugg, although they don't make actual appearances in the show.
Having enjoyed series like snowfall on FX, i found mcgraw ave to be a lower budget version of some of the same concepts and aesthetics. If you are able to tolerate the small doses of corny/cheesy content on snowfall, you will love mcgraw ave.
