Suspension of disbelief

So when obi-1 confronts Boba in the rain on the clone planet, boba flys off and shoots a missle at Obi-1 just missing him and little Boba uses the ships guns on Obi-1 and just misses him too. Ok heres my rant

If you watch the scene, little Boba stops firing for no reason, big Bobba seems to habe paused. If he cant take out Obi while thats happening, and little Bobba cant use those guns and auto locking and such, its not a great respect for the audiences

I fell if you go watch that scene, its a bit dumb how long Obi is exposed and should have died.

Yeah yeah its a movie, what other explanation is there, I get it.

Oh yeah, I think Boba needs to speak to Tony Stark about getting sum better missles, or can Jedi deflect the blast or use the force or do they just have tough skin.
