Really? I have no issues with it. Its a story, its based on a comic book and its entertainment. I enjoy every episode. I understand the repetitiveness but would rather have that than just the flash just pops in, gets rid of the baddie of the week then go home. Then the rest of the show would be filler and not be on tv for very long. Like most stories its a tale of aversion, overcoming that aversion and progressing.
Except it doesn't work when we have seen time and time again that he is perfectly capable of beating normal "slow" people without any issues as well as pulling of acts that require him to be faster than what anyone can imagine i.e.
- running so fast he can open a portal himself and travel back/forward in time (another thing that I never get, why there are moments where he needs the likes of Wally to open portals.....)
- running so fast that he can get 3 people in a room within seconds and they don't even realise what happened and as said, able to check an entire building out yet he can't check out the surrounding area to find a normal speed person....
- stopping a bullet from leaving a chamber i.e. that time Joe had a gun right to his temple
- can move so fast that he can cause not just the molecules of his body to phase through anything but also able to do it to anything and anyone....
- we have also seen what it is like from his perspective a few times i.e. everything practically comes to a complete halt
- moves so quick he can create an after image/speed mirage
Amongst many other things.
Either buff the villains/meta humans (so that they all automatically just have super quick reactions) or nerf Barry's speed big time. Can you imagine this happening for other super heroes i.e. batman, getting his ass handed to him by normal brawling thugs.
