1. It takes up a lot of disc space (for console gamers, specifically Xbox players.)
2. People would complain that it "ruins the immersion."
Now, I understand the first reason, but I just can't wrap my head around the second part. Yes, I love that the game is in "real time," but cut scenes can be an amazing tool to convey emotions or simply the level of the task that is at hand. Cut scenes can be used to develop the personality of characters, which is something I strongly believe that TES needs more of. Cut scenes took my breath away in other RPGs, and they have sparked emotions in me that TES just hasn't been able to do. Yeah, by having a predetermined cut scene, it chooses the outcome of the situation before you make any choice. But how does any choice effect the outcome of the current questlines? Plus, there can always be multiple outcomes, just look at DA:O. When done well, cut scenes develop everything in a game that an RPG should have.
That's just my 2 cents.
