In one respect I would agree with you, it is kind of weird. And it is no longer a true woodie. But....having been around the old Giant since it's opening, I can say that for myself, NTG is the evolution this coaster needed, from an aesthetic standpoint, it is fun to see and feel the "spirit" of the old Giant in this new form. Layout-wise the ride has only been altered to remove one circle of the midcourse double-helix and then drop the remaining helix to under the lift hill instead of around it
From the enjoyment angle, this ride has taken a giant leap forward. Compared to it's former (painful) Incarnation this thing is babybutt smooth, brighter,visually interesting, but most of all it is once again FUN!
Should every wooden coaster get this treatment? No. But if a woodie is structurally and ride-wise beyond hope, then RMC has provided an extremely viable option to destruction and removal.
