Another summer weekend and another round of nostalgic franchises hits the box office. This week Mission: Impossible and Vacation are back, though if you’re under 40 you probably weren’t pining for the return of the latter. A reboot of the 1983 comedy classic starring Chevy Chase, 2015’s Vacation doesn’t look like it will breathe new life into a franchise that has lain dormant since 1997. But first, let’s get back to the franchise that audiences actually care about.

Launched in the summer of 1996, the Mission: Impossible series has earned more than $2 billion worldwide, not adjusted for inflation. Though the franchise seemed to sputter with 2006’s Mission: Impossible III (directed by JJ Abrams), it bounced back in a big way in 2011 with Mission: Impossible – Ghost Protocol. The fourth entry in the series was embraced by both critics (93% on Rotten Tomatoes) and audiences (A- CinemaScore) and went on to become the highest-grossing M:I title of all time with $694.7 million in worldwide grosses.

So far, there’s no reason to believe that this weekend’s Mission: Impossible – Rogue Nation will reverse the trend. The fifth M:I earned an estimated $20.4 million from 3,956 locations on its first day in theatres, including $4 million from Thursday p.m. screenings. That indicates a first weekend of just over $50 million, or the second-highest opening in the series’ history after 2000’s Mission: Impossible II. Even more encouraging, Rogue Nation has garnered excellent word of mouth, matching Ghost Protocol in terms of its Rotten Tomato and CinemaScore rankings.

Now back to Vacation. The R-rated reboot launched on Wednesday with a disappointing $3.8 million. In terms of recent R-rated comedy debuts, that's lower than Horrible Bosses 2 ($4.2 million) and Tammy ($6.2 million). Like Vacation, both films debuted on a Wednesday and were distributed by Warner Bros.

Based on Friday’s estimate of $4.5 million from 3,411 locations, Vacation should stall at $13.5 million this weekend, or a total of $20 million in its first five days. That’s well below initial expectations, which had the reboot earning at least $20 million in its first Friday – Sunday frame.

Here’s Friday’s top five, based on studio estimates:
