I'm ok with directors taking freedom with the source material, it's actually more interesting than following it too closely (people mentioned Watchmen, but I thought it was already too similar to the comics to the point that watching it is redundant).
So to answer the question :
- Star Wars 8 : I did like the general idea of going against most expectations.
- Jumper : I never read the original novel, so as a standalone story I thought it was a good movie with cool depictions of "what would you do if you had that power ?".
- Death Note (Netflix movie) : unlike the OP, I had read the manga before, but I liked that the movie tried to play around with the note rules and imagine new ways of using it.
- Alien 3 : I watched the Alien movies out of order, I think it was 4 > 1 > 2 > 3. After watching the other ones, I got a bit frustrated by the repetitive tropes of the series, so it was welcoming to have the 3rd one subvert some of them (like "who's the android ?")
- MacGyver "new generation" : I'm not sure how the new series was received exactly, but one would expect fans to hate it. I actually like it a lot, even if it did change a lot of stuff compared to the original (some character motivations, more action and tech stuff, Mac is in a team instead of lone-wolfing all the time, ...)
- Troy (movie with Brad Pitt) : not sure one can say there's an "Iliad fan base", but the movie was criticized a lot for its focus on humans and flashy action, but it's a very enjoyable movie.
*edit
- Daredevil (Ben Affleck movie) : I thought it was cool, torn morality of the hero, cool depiction of his radar-sense, perfect Kingpin, ok-ish Bullseye (still better than the comics visuals)
- Thor 1 : great movie ; I get that fans would have liked to see Thor do more Thor stuff, but the story focusing on Loki's tragedy was more interesting.
