The dispensationalists seem to think there is plenty of detail, esp. in the OT.
Some, not all. The lunatic fringe as basis for judging the rest isn't a fair argument.
We've been down this road already back in 2004-5.
There are significant issues with the premil scheme that need to be addressed, such as the matter of who exactly inhabits the earthly millennium, the issue of sin, it effects and resolution, etc.
All of those things have been addressed in premillennialism - both historic (i.e. Ladd) and plenty with the dispensational side.
J.O. Buswell did some work on it as well (Bible Presbyterian Churches). Familiar with him ?
