'Fringe:' Tonight a must-watch...?

  I haven't paid much attention to "Fringe" this season, and I have only myself to blame for that -  too much TV, and only two eyes to watch it with. (Also two universes, but that's another story.) But I am reliably told that tonight's "Entrada" is worth every minute. (Posted below is a clip.)  "Fringiacs" don't need to be reminded - but maybe everyone else, myself included, does... Ch. 5. 9. My immediate thoughts? It's OK. A little dull. Much talking. Very little action.  But this is "Fringe:" Fine show, actors, writing.
