The only problem I had with it is the lack of a mask or anything to conceal his identity. I had a hard time understanding how he could keep operating without anyone recognizing him-- though, as others have pointed out, a version of L.A. with hardly any people does help..
Especially with Bill constantly addressing him as "Ralph" right there in front of the bad guys. You'd think Bill Maxwell of all people would have more regard for operational security. Surely code names are called for in this scenario!

And as we also saw, the vast majority of people he encountered simply thought he was a weirdo who liked dressing up in a superhero costume. Not very many of them saw him actually using any superpowers.
Indeed, there was that episode where Tony was suspected of torching a government records building and every federal agency was monitoring Ralph 24/7 since they thought he was sheltering Tony. There was a scene where Ralph tried to take off from his roof and fell facefirst on the lawn. The feds clearly saw Ralph in the supersuit, knew it was him, threatened to blackmail him by exposing his embarrassing habit, but dismissed it as just freaky behavior. You'd think somebody would've put it together with all the reports from bad guys about being caught by a curly-haired guy in a red supersuit.
