Justice League pretty much soured me on any future DC movies... Just like The Last Jedi did to the Star Wars movies, I've lost all excitement for both franchises... I doubt I'll see any of the new stuff in the theaters but will probably watch it once it hits Blu-ray or Netflix..
I have a gut feeling Aquaman is going to bomb.... Warner Brothers should just shelve anything DC related and have another go at it in 5-6 years from now with a complete reboot... but next time create a overall story arc that will span 20+ movies like Marvel did... It was obvious to me Snider and DC was just making ***** up as they went along...
They are hiring quality proven directors their movies will likely do well critically but it will take time for the financial part to catch up. They need to undo the mess they made.
