I think Dumbo has a good shot at being No.1 2 weekends in a row like you mentioned. I dare someone to make that club Dumbo 2nd weekend over Shazam 1st weekend.
I think the SLJ eye being scratched out by cat thing should've been kept to the Black Widow movie as I think that would've been a more suitable environment for the backstory for his eye rather than an alien cat infecting it. Other than that minor nitpick I thought this film was pretty good and I liked the 90s atmosphere they instilled in the film.
Another billie on the horizon for the MCU. Black Widow is one of the most popular MCU characters and her own long long overdue solo movie is going to be incredibly successful because of it.
Dr. Strange 2 should've been in 2020 November slot, it would be 4 years since the first one. Now if Nov 2020 is Eternals and Dr. Strange 2 is in 2021 that would be 5 years for a sequel. Surely that has got to be the longest period of time for a sequel to a CBM as of recently?
