Good call on "In the Heat of the Night."
"The Social Network," didn't ring my drama bell. The script was well written, and the characters relatable enough, but it's presentation as a... bi-o-pic... sort of set it apart from what I would normally classify as drama. The premise that "these are real people" kept me from suspending my disbelief in the more "dramatic" scenes.
I'll stress, though: not a bad movie.
