Easter Egg theme. Movie titles with all the letters of "easter egg" added, one at a time to each theme answer, to make funny alternate titles. There were some clever theme answers, I guess, and there are, what, nine of them? Plus the "Easter Egg" one? That's a lot of theme, it seems to me.
I kind of hate the "Part of, abbr." clues, like 53A: Part of E.M.S.: Abbr. = EMER, and 40D: M.I.T. part: Abbr. = INST. 123A: Part of N.B. is slightly better, because in the first place it uses the whole word in the answer, and in the second place, this particular answer could either have been NOTA or BENE.
My favorite clue might have been 78D: Solo companion. We thought a long time about what that might mean, before finally realizing that it used a hidden capital, and the answer turned out to be CHEWBACCA. Gotta love seeing Chewy in the grid.
Aside from that, though, there wasn't a whole lot that I loved about this one. It wasn't bad, it just wasn't great.
