As a film fan and not a reader, I dont really care so much about true adaptations as long as films are executed well - I dont think Conan ever claimed to be one either. It would be easy to pick fault with the X-Men films for that, but the films are good without having to stick 100% true to the comics.
I totally agree. I think its a bit sad when comic / book fans complain that a movie isnt "true" to the source. A movie is different medium, its going to be changed and adapted. Enjoy it for what it is, not what it might be.
