I've had to space my viewings out over the past year for any and all the Toho movies dear to me. I feel like that if I get away from them for awhile (though NOT all together, just not back to back!!), the force behind them won't be spent. It gets pretty rough when all that gets you off are a handful of Showa movies, and that's where I was headed.
Gotta preserve that sense of AWE.
