Aside from there being no good reason to believe in any literal fulfilment of the claims in Revelation or the gospels about resurrection, the JW interpretation is especially flawed. The Bible doesn’t say that anyone is resurrected during the thousand years. It says the first resurrection before the thousand years is that of the great crowd - the people from all nations who serve as kings and priests for 1,000 years. The Bible also suggests the 144,000 are only resurrected after the 1,000 years, and it says they serve as kings without any mention of them being priests, and they rule with Jesus forever.
