To be fair, the force fields did show us a little about the Jedi characters - Qui Gon's patience vs Obi Wan's impetuousness

Another oddity of the writing, given that the entire movie up until that point was showing us that Qui Gon was impetuous and Obi Wan was patient.

Good point. My understanding was that originally Obi Wan was the only Jedi in the film - and was impetuous, to match what Ben said in the OT - and then it was re-jigged when Qui Gon was added; perhaps this is a remnant of that.
