He tracked the Sandpeople? By what means? Considering his mother had been gone for a month, he's going to have a heck of a time trying to find their trail in the deserts of Tatooine. The lightest bit of wind will eliminate any evidence or tracks in an instant. I have no doubt that he might have checked in with any locals he ran across to make sure he was heading in the right direction, but, if you've ever been in a desert, try finding anyone through sheer luck alone. It's highly unlikely. And he also must have used the Force in at least one instance -- he was able to find Shmi's tent on the first try. He didn't have to check every tent in the Tusken camp to locate hers in particular. Also, why in the world would you presume that Vader, upon seeing a ship departing, would not scan the ship for any recognizable presences? This seems the most logical course of action considering that he is gathering information on his enemies. Also, even if the ship is taking off, I'm sure it's not going at several hundred miles per hour as it needs to accelerate (although let's not turn this into a discussion of the physics of Star Wars -- we won't get anywhere there! ). I don't see what the ship being sealed has to do with anything either. The Force isn't like sound waves -- it doesn't need a medium to travel through, so I'm sure he can sense things in a sealed chamber just fine. Checking the ship over since he's there and it's an enemy vessel seems only logical to me. Why would a week not be enough time for Vader to learn to recognize her presence? The films have never established any sort of limitation on this. And Vader has a vested interest in remembering Leia -- she's not some random trooper, she's the head of the opposition. I'm not suggesting that the Force acts as a radar, I'm suggesting that if Vader consciously scans the ship for familiar presences (because he's right there and he loses nothing from doing so besides gaining information) that he would recognize Leia. It's also certainly possible that Yoda, as a powerful Force user, could shield his presence from Palpatine. I'm not quite sure what you are referring to considering Jango. Obi-Wan was not in close proximity to Jango until he arrived on Kamino. In a nutshell, my argument is that if Vader is inspecting a known enemy ship for information on it's occupants, he would recognize untrained Leia. I don't see what's problematic about this. What leads does Vader have to try to find Luke? Seriously, I'm interested in hearing your answer on this because I'm not sure what they would be. Vader initially knows that Luke is with the Rebellion, but when they evacuate, how does he know where Luke will go? I actually think he does search out the Force looking for answers (hence why we see him meditating), but he's not going to find Luke because he's with Yoda. Also, who says he didn't interrogate anyone from Hoth? They obviously aren't going to show it in a PG movie though. But consider that no one knew where Luke was going -- he never told anyone and even R2 was surprised by the change in direction. So even if the Rebels were interrogated, they wouldn't have any information to give Vader. Leia herself is valuable, so Vader is going to try to capture her, especially since he's actually seen Luke in her presence. Besides her, Vader has no leads as to who Luke might be friendly with. Or maybe those interrogated Rebels told Vader that Luke cares for Han and Leia most and that they are in the Millennium Falcon -- that would certainly explain Vader's pursuit. I find your criticisms peculiar because you seem to be asking to be spoon-fed the information by the film. If something isn't shown onscreen then apparently there is no way for it to have happened. But the audience doesn't care about random Rebel #25 who gives the Imperials important information. What makes for good entertainment is seeing how they act on that information. Is it really such a stretch to believe that Vader could get information of Luke's close relationship to Han and Leia and then chase the Millennium Falcon as a result, considering it's Han's ships? There are plenty of possibilities and it's not a plot hole simply because it isn't spelled out onscreen.
