I have to agree. I just watched "Q Who" and the scenes where the 1701-D is slowly flying away from the camera into space you can see, that the nacelle lights pass isnt quite stable horizontally. At some points the nacelle lights move slightly left/right away from the models nacelles. HTV didnt even made the effort to stabilize the nacelle light pass.
Seems like HTV must have scored this contract based on Curry's reputation and his involvement with the original run of TNG. The team working under Curry's supervision at HTV clearly lacked the required experience to pull off a project of this complexity.
I'm sure it must have been a painful learning experience, for both CBS and HTV.
I have to wonder if the fans speak loudly enough, would CBS consider going back and refining things on Season 2? For such a historical project, it would seem wrong to leave Season 2 in this shape. Not only do the new S2 effects lack CBS-D's fine polish, they lack an overall professionalism. I'm gobsmacked that this was ever allowed to happen.
