Movies with either Marisa Tomei, Sandra Bullock, or Rachel McAdams should not be allowed to miss. Unfortunately, About Time does. It is nothing to one's understanding of time-travel movies, and it's endless attempts at tender moments becomes tedious. Even as a half-hour television sitcom it would not make it. As a seemingly 10 hour feature film, it's numbing even if many of the characters are actually likeable.
