These are just my opinion. If you disagree, to each their own. Please forgive any errors as English is not my first language.
The Time War was a great idea at the start. It refreshed the mystery behind the Doctor's past and added a new layer of depth to his character. What was the Time War? What was the Doctor's role in it? Questions like this kept the "Who?" In Doctor Who. But Moffat diminished all of that by showing thw war. Thus taking away the mystery behind it. This huge unimaginable war is shown to be a Star Wars-esque battle that pretty much anyone can imagine and it's quite disappointing . Some things are more effective if they are not shown.
