Jeffrey Blitz’s Table 19 (D+) is a few chairs short of a winner. Despite the presence of Anna Kendrick, Craig Robinson and Lisa Kudrow, this comedy about mismatched guests at a wedding table never fully gels in its attempt at droll observational humor. The characters are implausible and their actions unmotivated. The director, along with the DuPlass brothers, famed for their mumblecore films, can’t cobble together a worthy script for this ensemble. You’re just waiting for them to knock over the cake and be done with it. The film is a good choice if you’re trying to fall asleep on a plane.
