Saw the movie again Thursday afternoon and liked it even more the second time (better sound system helped, too). Our auditorium was pretty bare, but it was a weekday matinee, so not unexpected; as we left, the place was crawling with families there to see the early showtimes of Mario.
I suspect D&D will get slammed by Mario this weekend and land at second or third, depending on how John Wick does at this point of its run. [EDIT: Ah, forgot about Air, as others have mentioned! Yes, also probably a factor.] Best case scenario might be it bounces around the Top 10 due to the good word of mouth until the full-on summer blockbusters start crowding out screens and it winds up with a respectable, if unremarkable, total gross. Paramount/Hasbro wind up with a modest hit that builds up some goodwill with general audiences and primes them for an easier-sell sequel and/or the franchise expansion they've already talked about. At the absolute very least, the PTSD from the 2000 movie goes away thanks to a well-liked reboot.
That's my take, anyway.
