I don't say you are wrong but I unfortunately didn't really get a friendship vibe in AOTC either. They care for each other, yes, but they also both act like jerks and don't seem to care when they hurt the others feelings. It even reminded me of a marriage where both partners secretly hate each other a little but still don't find the courage to go separate ways. I viewed AOTC twice (by far my least favorite star wars movie) and I just never really "felt" any real friendship. That could've do do with a couple botched lines too, of course. Sure, it can be interpreted this way. It can also be interpreted in Obi-Wan wanting some revenge on the pupil who disappointed him. Considering OBWs current state of mind, this interpretation is not that far off. But on total, ROTS has made me rethink my stance on Obi-Wan somewhat, and also on Anakin. If I ignore AOTC and include some of the EU in my personal canon, I even like them both.
