The problem I had with them was that, even as a kid, it seemed to me that the filmmakers were embarrassed by the character's comic-book roots and seemed to determined to minimize the comic-booky elements as much as possible. Hence, no costume, no Red Skull, no Hordes of Hydra, etc. As I recall, they generally avoided calling "Steve" Captain America wherever possible, and only did so sheepishly at best. "Maybe you can be some sort of, er, 'Captain America' or something." That kind of thing.
Compared to the CAPTAIN AMERICA comics I reading at the time, it all seemed rather mundane and timid.
By contrast, the DR. STRANGE pilot, despite its limitations, embraced the wilder aspects of the original comics: you had astral travel, visits to strange Ditko-esque dimensions (as much as a limited tv-movie budget would allow), demons being summoned, ageless sorcerers throwing spells at each other, even a fairly accurate recreation of Strange's Sanctum. As opposed to all the other CBS productions of the time, which sometime seemed determined to cram larger-than-life comic book characters into "Barnaby Jones"-sized plots, DR. STRANGE at least tried to capture the feel of the comic book . . . .
