The Questions that Enter Every Fan's Mind (probably)
If you look at it logically, the moment that Hayata first learns that a monster is threatening to take over earth or is on the rampage, he should use the Beta Capsule as soon as possible to become Ultraman and remove the threat quickly. Also, as Ultraman he gains nothing by fighting the monster in a physical confrontation. To minimize death and destruction, Ultraman should use his specium ray or other means to kill it quickly.
Obviously the show would not have been as fun and exciting. I wonder if they could have addressed these questions in the plot in a way that made sense?
