Reviews are starting to roll in for Will Ferrell and John C. Reilly's "Holmes & Watson," and critics don't have too many kind words for the comedy flick.

The movie, which was released Christmas Day and wasn't made available for review beforehand, parodies the Sherlock universe with the duo you know from "Step Brothers" and "Talladega Nights."

Now that critics are watching along with the moviegoing public, their reaction isn't great: The movie has zero percent favorable reviews on Rotten Tomatoes and just a 16 percent audience score.

The Hollywood Reporter's Frank Scheck called the movie "devastatingly unfunny," adding that "the overall shoddiness is typical of this feeble sendup that doesn't even manage to be as funny as the recent Benedict Cumberbatch and Robert Downey Jr. versions."

IndieWire's David Ehrlich wrote that the movie's confusing attempts at humor felt "like it's leaving an all-you-can-eat buffet on a full stomach."

"Instead of picking a particular tone and wringing it for all it’s worth, (director Etan) Cohen just throws a mess of half-funny jokes at the wall in the hopes that some of them might stick. They don’t," he wrote. "Not enough of them, anyway."

"Glad I saw #HolmesAndWatson before I finalized My 10 Worst Movies of 2018 list," critic Jackson Murphy tweeted.

Other critics lamented the fact that they had already released their "worst of" list.

"It belongs at the top," wrote AV Club's Ignatiy Vishnevetsky.

"One might call it a failure on almost every level – that is, if the movie ever gave the impression that it was trying to succeed," he said. "Instead, it’s pervaded by an air of extreme laziness. It’s cheap and tacky ... poisoned with rib-elbowing topical references and puerile gags."

"#HolmesAndWatson was one epic pile of cinematic disgrace and an insult to the legacy of Sherlock Holmes," wrote critic Danielle Solzman.

"More laughs are all that would have been necessary to prevent the stagnation of 'Holmes & Watson,' wrote Ben Kenigsberg of The New York Times. "As the movie stands, smuggling in booze to dispel the sense of dull routine could only help. Sony sneaked this parody into theaters on Christmas without screenings for critics, normally evidence that the film in question is less than the work of a mastermind."

Not everyone felt the movie was a flop: Entertainment journalist Simon Thompson argued the movie was "as stupid as it (is) smart and that's a good thing."

"Way funnier than I expected it to be, way funnier than perhaps it has any right to be," he wrote. "Not perfect but I laughed a lot."

"One doesn't need to be a master detective to deduce that 'Holmes & Watson' is a dud," wrote Variety's Peter Debruge. "Sherlock Holmes exists so large in audiences’ minds already that the pair’s uninspired take feels neither definitive nor especially fresh – just an off-brand, garden-variety parody."
