LIGHTHOUSE IN THE SEA OF TIME

This is a good ep with a message that had the potential to be quite preachy. I'm glad you guys avoided that for the most part (I'll get to that later).
Yeah, Macbeth as the villain was pretty much tipped off at the beginning. It indeed would have been better if we had suspected Xanatos as the villain all through Act I. At least we got some dramatic irony out of the situation.
Anyway, Macbeth is always a good villain--and you just can't beat his first appearance here. The "Macbeth Theme" comes up in the background (and I love it, too), the lightening flashes, and Macbeth walks towards the screen. You'd have to go a long way to beat that. And I did associate that "Electricity Gun" (as I called it) with Macbeth (he and his flunkies were the only one's who used it).
Actually, Banquo and Fleance were pretty good too, as far as henchmen go. They had their own personalities and B.J. Ward and Frank Welker did good work with their voices. And yes, I have to smile when B.J. Ward talks to herself in the ep.

Animation-wise, I don't suppose it was too bad. *I* thought Elisa looked cute with the red cap. Though how she managed to yank it off without pulling out her hair (since she put it through the hole in the back) is beyond me.
I noticed that Goliath visited the Eyrie building and confronted Owen again (only this time with Brooklyn and Lex in tow), but it works for me.

Robbins...a great addition. Paul Winfield (that is his name, right?) did a great job on his voice (you were going to shoot for Ray Charles?), and his lines were very well written. I find his exchange with Hudson about the phonebook and his final monologue to be some of the best lines in the series.

The opening prologue with the archeologists (after looking at the credits for so long, I knew they were named after your writers and staff) serves it's purpose. The lyre's role is fairly easily deduced, and the full import of the spell on the chest becomes apparent in later viewings. But I agree it would have played better as you described it.
The Scrolls themselves presented a wonderful "Left-turn in the last Act" so to speak. I was quite surprised myself that they turned out to be a diary, and I have to agree that Merlin's Journal would indeed be priceless. I was pleased at the revelation.
I did think along with everyone else that Macbeth had sealed the Scrolls himself. Maybe knowing so little about Macbeth would make us latch onto anything that could even be remotely considered a clue. In later viewings I understood it, though.

On the moral itself...like I said, I felt it was very well done. I didn't find Goliath's mentioning the "library downstairs [being] full of books about [Merlin]" to sound like those Public Service announcements at all. Maybe it's because I don't pay any attention to them or because it just sounded like something Goliath would say (I mean, he loves reading). And I love how Hudson's illiteracy is revealed and handled. I felt it was quite moving. And Macbeth's speech about Arthur was good too. However, Broadway's growth is where I enter into a more grey area. I felt it worked quite well for the most part, especially his line "When your life is this exciting, who needs books?". However, his last speech...I suppose it isn't so bad, but it did seem a little thick with his expression "They take you there". It is true, and probably the best thing to say, but I just can't get into it. Maybe I'm just too used to reading to be able to fully empathize with Broadway's sense of wonderment.

Still, an ep I enjoy wathing. I just wonder how Broadway was able to rip open the hull of the harrier without any noise.
