I have a soft spot for David Tennant's Doctor, but that's just because he was the first handsome and respected character I've seen stimming on film without it being played for laughs. Same thing later on for Lee Miller's Holmes on the CBS Elementary series.

I guess Tulip from Infinity Train feels close to how I view my younger self in an adorable way.

But in general I try to avoid being uncritical of characters in media. I see them as being inspired by our reality (and critique it in that direction) rather than as ideals to emulate or actual facsimiles. I find it way more interesting when they aren't in fact "literally me" and deviate from the similarities at some point.
