Were you one of the millions who took a boat ride on ABC's new series "The River" last night? 


The two-hour premiere debuted with mixed ratings — averaging 7.5 million viewers, but "a meh 2.4 rating in the adult demo," according to EW.com.


"Moreover, the show lost a 10th of a rating point each half hour during its run," the site adds. "The news is a bit surprising considering how successful ABC has otherwise been at launching new shows this season, often delivering stronger premiere ratings than expected."


The network has been building buzz for the series ever since it won a bidding war for the show against NBC in late 2010. In a nutshell, it follows a family's efforts (who in turn are followed by a documentary film crew) to track down their father, a famous explorer and television personality. As you would expect, things don't go according to plan — with some supernatural elements mixing suspense with horror. 


“Every episode stands on its own as a mini horror movie,” creator Oren Peli ("Paranormal Activity") tells the NY Daily News. “So even if you’re not watching the entire season and you just jump in, you can enjoy the episode on its own."


Reviews of the series have tilted mostly positive, with TV Guide's Matt Roush calling it "a terrifying heart-stopper, a cleverly cinematic supernatural adventure that takes us on a wild ride into an exotic heart of darkness." Others, such as Maureen Ryan of the Huffington Post says it's yet another example of ABC trying desperately to replace a former massive hit. 


"'The River' isn't terrible," she says, "and it actually has some effective elements, but it's fairly indicative of ABC's post-'Lost' flailing.".


What did you think? For those not already on board, have a look at the trailer for the series below. "The River" airs on ABC Tuesdays at 9 p.m. E/T.
