Awful script writing. Obi wan has just moped about in the desert for 10 years, has done no training with the force.
Don't get me started on the chase scenes involving leia.
Leia is supposed to be 10????
At the end of episode 2, obi wan basically escapes on the number 7 bus, whilst the inquisitor (3rd sister,who has the entire empire at her disposal) just shakes her light sabre in the air., watching the bus slowly fly away, terrible.
