The problem with the new series is that the source material doesn’t provide a lot of dialogue to draw from. This means that the screenwriters created new dialogue for the show. However, it feels stilted and at times ridiculous as though they’re attempting a medieval reenactment.
While they are attempting to maintain consistency with the rest of the GOT universe, it doesn’t come across well. Few of the characters have the chops to maintain the viewer’s interest. A scene between Daemon and Princess Rhaenyra came across as forced and awkward (via Marie Claire).
