Fans of the TV series “Underdog” that ran in the mid-sixties may be a little skeptical of the latest release by Disney Pictures, but it still delivers some fun moments. Critics aren’t going to give the new film adaption of Underdog a Best in Show prize, but it can still entertain young fans. This is the trend for Disney pictures nowadays, taking a tired idea of the past and trying to revamp it for modern audiences. Some characters like Underdog simply age terribly and can no longer captivate an audience. This is the case for this old dog, who is one step away from getting put to sleep.
