Ahem....
I find this, as a boss more original than....
Generic Giant Guy.
I never found the original games to be at all scary, I like the setting and the monster designs(No, not including the Zombies) more so than the later games. Resident Evil 4 is probably my favourite overall. I find Resident Evil 5 to be an unplayable piece of trash because of how dumb the Partner AI was, she was seriously beyond fuckin brain dead(FUCKIN USED UP ALL HER BULLETS!!). Resident Evil 6 was...I enjoyed that game more(it's still bad, but in a good bad sense), plus the option of giving your partner infinite ammo was the greatest thing they improved on from 5.
I still think Resident Evil had the best boss; Nemesis. The one boss in the original trilogy I encountered that made me experience true horror. And Capcom hasn't replicated him at all, which is sad really.
As for the Resident Evil Movies.....Even as Action Movies they were really bad. The last movie was beyond garbo, LETS JUST RANDOMLY BRING BACK DEAD CHARACTERS BECAUSE THE OTHER MOVIES WERE GR8 RIGHT? RIGHT?!
To be quite honest, Silent > Resident Evil when it comes to horror and gr8 monster designs(Without them looking super dumb.)
