This is neat

bad engineering. the chances of dropping his dna into a raging ravine can spawn homosapiens is as almost impossible

Well Dr. Henry Philip McCoy (in fiction) is not a world authority, any established science authority need a commitee of many members. I'm however, a doctorate in the same field as the fictional Dr. McCoy.... the real McCoy, pun intended.

It's a shame that X-Men 1/2/3, First Class, XO: Wolverine ... all commit worst offences..just make the movies so much less enjoyable.

However, movies that categorized themselves in the sci-fi genre, are assumed to have scientific basis, else they can be called fantasy.

I'd would not say bored.... It just makes it less enjoyable.... Avatar and Avengers were great....
