I don't mind cut-scenes in a game, but they shouldn't disrupt the pacing of the gameplay. I can forgive a lot of them or long ones if the flow of the game isn't messed up, but even if there are few or short ones, if they mess me up, I'd rather not have them.
There should be save points before the long ones in any case...I remember a few instances in the FF games where I'd just gotten through a tough situation like a boss battle. And then, over twenty minutes later, I got a chance to save. My obsessive-compulsive nature of constantly saving, especially before and after a tough battle, makes it harder for me to enjoy what could be a good scene if I'm thinking "LET ME SAVE" all the way throughout.
For scenes that are eye candy, I don't understand why these games don't have an option to let you view them all again, even if you have to switch discs to do it. Eternal Darkness had that option, except it for some reason missed one really cool scene, sheesh.
And then there's Custom Robo. Boy, a Nintendo-developed game is one of the worst for exposition. I like saving, as mentioned above, but if a long single scene near the end of the game has three points where they let you save, and it's just a big long scene of talking, you know that's a pace-killer. On a related note, it had a nice opening FMV sequence, but they should've put some of those explosions in that big long blah-blah-blah scene to wake me up.
