The animated adventures of Doc and Marty were a great way to continue the series, however a few things could've helped. First of all, only a few cast members from the films returned to voice characters, which is a shame. The only time we see Christopher Lloyd as Doc is in the wrap arounds, and the voice of Doc is provided by Dan Castellaneta (the voice of Homer Simpson). It probably would have been a more successful show had Michael J. Fox also returned as the voice of Marty.
However, the true fans are still happy with the result, and the show has a sort of cult status. The fact that CBS only seldom aired reruns, the audience wasn't wide and many fans of the film series hadn't seen this show. Thankfully, the whole series is now available on dvd since 2015, the franchises 30th anniversary.
