Contradictions and inconsistencies...
Just rewatching the series again, and time and distance has helped me see how inconsistent this show was. Yet I suspect die-hard fans would say there aren't inconsistencies and that Lynch had it all worked out. Still, here are the ones that really irritate me:
1) Pretty much everything Bob did after he killed Maddy. For someone who tried to keep his existence a secret, he sure was trying hard to show Cooper the golf bag where Maddy's body was hidden; he toyed with Laura for years before he killed her but was going to kill Donna a day or two after he killed Maddy; why does an evil entity like Bob only kill pretty young women? I guess evil entities are a lot like your typical serial killer.
2) The Tremonds can apparently be seen by anyone, yet Bob can't. Then when they disappear, no one tries real hard to find them.
3) Albert doesn't believe Bob exists, but saw Agent Jeffries disappear in front of his own eyes in Fire Walk With Me.
4) Why would Bob take Ronette with Laura to the train? Why wouldn't he just leave her at the cabin? He didn't want Ronette, anyway.
I'm not trying to be a jerk, it's just interesting to see how much they were making it up as they went along. What other inconsistencies did you guys notice?
