The last E3 trailer was kind of choppy looking back on it. However, it was vastly improved by the gameplay trailer that came after that. However, the environments still looked dry in the second gameplay trailer. They fixed that with the colorful amusement park montage trailer. Right now, I don't see how they can top the latest trailer. It took everyone by surprise, and now, I don't think there's anywhere to go but down. Only a Vergil reveal could top that, in my honest opinion.
I didn't really like the over-the-top situation that made New Dante look like DMC3 Dante, especially the pose at the end. However, the reactions were mostly positive, so, maybe it's for the best and Dante is still serious with only some humor. He had no cheesy one liners (the "bad day for a hangover" line was just him mumbling to himself in a Nick Nolte fashion simply because he was hungover.) so far, so let's hope they didn't "tweak the script" and kept only the good lines in there.
The "church" line was merely a commentary on how boring church was. It wasn't cheesy by any means. It was clever because it was true. It didn't need to be laughed at, just acknowledged. Church does drag, and inside Limbo it did seem like there was no end to it, making it an apt observation.
