I feel kind of bad for writing this, since it was a generally clever and well-written episode, but I didn't really like 302. I felt like jumping back and forth through the reels allowed for clever puzzle design, but that it didn't do the story any favors. I had assumed Sam and Max were "reliving" Sameth and Maximus' adventures, but there are too many plot holes in the story for that to make sense
(like singing Amelia to sleep with "Flight of the Valkyries". How the heck would they have known to do that short of time travel?) and all the jumping around made the story harder to follow without making for a more interesting telling
(like finding out Nefertiti had a crush on Charlie Ho-tep before I had met her the "first" time which just came across as confusing). I think the basic plot was interesting, but the way it was revealed was awkward. I think it would have been easier to follow the narrative if it had unfolded linearly.
If it had been that Sam and Max weren't just watching the story unfold, but actually inhabiting their ancestors and experiencing it for themselves I think it would have worked out better. Instead of Sammeth and Maximus
experiencing puzzle-dependent amnesia when it came time to escape Kringle's attack in the tomb, it would have actually been Sam and Max going, "How did our great-grandpas get out of this one?" Sammeth and Maximus acted exactly like Sam and Max anyway, so it wouldn't have been that big of a change.
Of course, I'm the anal-over-analyzer type, so I'm probably the only person bothered by this kind of narrative nitpickiness!

And I still like that they decided to do something different with this episode. The fact that they're not content to just go with the same old, same old is one of the things I love best about Telltale after all.
