For a while now, The CW’s annual mashup of its superhero franchises has been getting bigger and bigger with each installment. But now that the numbers from this year’s debut night of Crisis on Earth-X are in, we’re finding out just how big the network’s tentpole event has become.

This week’s two-installment debut of Crisis on Earth-X drew The CW more Monday night viewers than it’s seen for any program in the same time timeslot since 2009, according to Variety’s early breakdown of Nielsen ratings for the evening.

In the prime 8-10 p.m. time period, The CW saw an average of 2.6 million viewers. That includes a 0.9 rating for Supergirl at 8 p.m., as well as for Arrow at 9 p.m. in the 18-49 year-old viewer demographic — the highest rating of the season for each show.

The Nielsens were almost as strong in the tighter 18-34 year-old demographic, averaging a 0.8 across the two-hour window.

This year’s crossover brings Supergirl, Arrow, The Flash, and the Legends of Tomorrow crew up against their evil Nazi doppelgängers, raising the stakes to absurd levels, while leaving plenty of room for some much-appreciated lighthearted moments.

The one-two punch of this year’s debut episodes left off Open eyeClose eye Show Spoiler with the good guys locked in captivity on Earth-X, and STAR Labs under Nazi occupation. With cliffhangers like that laying the groundwork for the second — and final — night of zaniness, we won’t be surprised if The CW’s ratings for night two of Crisis on Earth-X end up looking a whole lot like an encore performance of night one.
