Casting Stalone as Judge Dress was bollocks too.
What's your list of popular films you have never seen and have zero interest in.
Harry Potter (never seen any or even wanted to)
Star Trek ( Never seen any Films or TV shows)
Any Bruce Lee film
The Princess Bride
Paranormal Activity
Blade Runner
Guardians of the Galaxy series
Tron
I.T (original and remake)

If you were a fan of the Dredd comics, you'd appreciate the horror at casting Stallone.
Actually, you never see Dredd's face, but in the movie we see Stallone's face constantly. Why? Because it was purely a vehicle for him and his star power. And it failed miserably.
I guess if you watch it (and the Reacher movies) without prior knowledge of the source materials, you can appreciate them without any bias or expectations, and judge them fairly. But i couldn't do that for these two.
