Obi-wan, knowing that for the past 10 years Jedi have been hunted, still doesn't see the trap, then goes to a spaceport dressed up as a Jedi wearing his lightsabre openly and then, after turning up to the big city and finds out about the bounty on his head, still runs around with his hood down so everyone can see his face - Wow, great storywriting!!!
Never mind that Leia can outrun adults, never mind the sudden "roof top fight" which stopped the instant the story needed Leia to talk to Obi-wan, never mind that Sen. Organa didn't send his own people after his daughter, or that he knew exactly which cave Obi-wan lived in etc etc - Jesus the story-writing was so bad!
