I don't mind cutscenes (even lengthy ones) as long as they don't get in the way. Eg, No One Lives Forever had some lengthy cutscenes but you could both skip them plus they were funny. What irritates me the most is actually the short but unskippable "micro-cutscenes" in modern "cinematic" games, ie, the ones where every... trivial... action, picking up an item, pulling a lever, opening a door, using an item, stepping over a pebble, etc, will trigger some 2-5s "cinematic" which over the space of a mission will constantly "snatch" control of the player back & forth dozens of times. Just show me a pre-mission briefing video then let me play the damn level continuously (which I find 10x more immersive than "over-scripting" that constantly stands between the player and the gameplay).
