I enjoyed the first entry for N64, felt that while it wasn't a great Castlevania game, it was a very competent 3D action platformer.
While I never played the 2nd one I thought the first PS2 entry Lament of Innocence was decent. Nice graphics and decent Devil May Cry type play control (did every game between 2001 and 2007 play like Devil May Cry?).
Didn't LOVE either, but they were enjoyable romps.
