The decision of later productions to ignore the force field belts was what created the continuity problem.
Technically correct. But already as a kid, having watched TOS, I thought these force field belts not to be believable. They seemed to be goofy and after TMP they definitely did look goofy. And I'm quite relieved they used real EVA suits in TMP or could you imagine Leonard Nimoy in TMP just floating around being surrounded by a glowing energy field? (He wasn't a Q)
Just my personal opinion.
