The 32-year-old actor, who played Charlie Pace on the ABC cult series, also said that he knows a few details on how the series ends.
"I know little bits and pieces about the final season, but I'm still going to watch it," he said. "It's event television, so I'll definitely be tuning in."
Asked about the comparisons between Lost and his new series FlashForward, Monaghan claimed that there are "distinct differences" between the shows.
"Well, there are obvious similarities because both Lost and FlashForward include a large ensemble cast, a very ambitious storyline and a very easy way to sell the show internationally because it's based on an event that happens worldwide," he said.
"Both include mystery, drama and suspense - but at the same time, I think there are distinct differences. I think FlashForward is a show that is probably not as sophisticated in that deeply-rich mythology as Lost is.
"However, I would not like to call FlashForward ‘simplistic’ in any way."
Lost returns January 2010 for its final season. FlashForward currently airs Thursdays at 8pm on ABC in the US and Mondays at 9pm on Five in the UK.
