The Blu-ray rip is only marginally better than the broadcast HDTV-rip.
(The Blu-ray rip is 1280x720, which means it is 720p, not 1080p.)

Magic circles look cool when they are new, but now they are way overused. They should be reserved for really powerful spells. They also look a bit silly when not on a surface.
