I find some bluray ether too dark comparing some generation of laserdisc to DVD to bluray (some).

A lot of these problems can be down to the fact that many laserdiscs were overly bright due to the telecine process but also can be down to the colour range a player uses for blu-ray. Some players will default at 0-255 for blu-ray and this can look too dark if watched on a CRT or older LCD/PLasma that don't support the extended range. Whereas DVD should play at 16-235 which is the range both DVD's and Blu-rays are encoded at. If you player has an extended range setting in its setup then disable it and you'll notice a big difference. But the last thing si that its a fad with hollywood at the moment to crush blacks to give deeper black levels when transferring a movie. This is more than evident on the Star Wars DVDs so it's nothing to do with Blu-Ray as its been happening on DVD for a while now
