Yes, those were blatant rip offs of TWOK.
What I didn't understand was why JJ Abrams chose to do another movie that featured the Khan character and that was based on TOS's "Space Seed". I take it that STID was, more or less, JJ's sequel to "Space Seed". But why do another one? There is already a sequel to "Space Seed". It is TWOK, which btw is an exellent movie and very good sequel as well.
Compared to TWOK, JJ's version of a sequel to "Space Seed" sucked. In any case, STID was mediocre even without the comparison.
If JJ wanted to evoke nostalgia, why didn't he choose to base his 2nd Trek movie on a different TOS episode. There were over 70 other TOS episodes that he could have chosen from.
