The live action footage looks great, there's no doubt of that. For most of the second season the actors looked like they suffered jaundice, now the skin tones and colours are better than they have ever been. The issue with the effects I feel is that CBS-D where faithful to the original, but improved and modernized them significantly at the same time. The same cannot be said from what we've seen so far from season 2. The new effects are practically carbon copies of what we had before but with clarity. The planets still look like they were produced in the 80's instead of the superior mattes produced by Max Gabl. The star fields look poor in comparison to the 'ILM stars' used in season 1.
Plain and simple, there should be somebody at CBS D who works with the people at HTV Illuminate to minimize the differences in the work they produce that affect the quality and continuity off the effects shots between the seasons. None of us really wants a repeat performance for season 4.
