I agree with most of what you said Gok, but disagree on the costumes part and would point out:

1. Jedi Robes looking like they do was established back in the original trilogy; if you recall at the end of Return of the Jedi, the ORIGINAL Anakin Skywalker Force ghost (portrayed by Sebastian Shaw) is wearing the same Jedi Robes. The same could be argued for Yoda?s outfit in ESB, though less obvious.

2. Obi Wan?s costume in the series is definitely not the full Jedi outfit - he has what is probably a generic hooded robe, but the underlayer is definitely different. So there is some attempt to disguise himself. Plus, as you stated yourself, the Jedi outfit is a common looking outfit. Hiding in plain sight especially on Tatooine clearly worked for Obi Wan.

I just watched the opening sequence with Order 66 again and thought it was awesome, though on reflection it doesn?t make sense that the Jedi Master is doing Jedi-Chi completely oblivious to the chaos and death of Order 66 happening at the same time.

I also have questions about the hygiene practices of Obi Wan?s meat processing plant
