Critical reception Coma was met with generally mixed reviews. On review aggregator website
Rotten Tomatoes, the miniseries holds a 50% score, an average rating of 4/10 taken from reviews from 20 critics. Its consensus states: "
Coma evokes some creepy images but the majority of the miniseries is not believable in terms of story development, dialogue, or performances." The miniseries received a 56 out of 100 aggregate score, based on 16 critics, indicating "mixed or average reviews" reception at
Metacritic. Clark Collis of
Entertainment Weekly gave it a B grade, but added, "Alas, there are enough reminders of real life—including an early suicide—to dampen the fun of this guilty pleasure." Verne Gay of
Newsday also gave it a B and stated, "The plot's ridiculous, but the film's mostly fun, while the pleasure of watching
Ellen Burstyn play a homicidal wacko is not to be denied anyone." David Hinckley of the
New York Daily News stated, "This
Coma is different enough from the
1978 movie to have its own appeal, and the cast keeps things interesting even during plot lulls." Linda Stasi of the
New York Post called the miniseries "very lame" and "dopey", adding, "The mystery is pretty much laid out like a coma patient from the beginning [and] ruins whatever suspense you might otherwise have built up." == DVD release ==
