Absolutely, we form such weird attachments to things we saw as kids that we don't really remember well at all.

ST:TOS I highly recommend because it remains engaging/entertaining and is fascinating to see as a lens into the late 60s, but "good" it is not.

ST:TNG I love and I think is the better show but it shocked me too when I tried to rewatch in order after ST:TOS. The first seasons are not great! I really had erased a lot of it from my memory. I realize now that it's not until a couple seasons in that it became the show I remember, that show was lucky to hang in there long enough to hit its stride.
