It's a straightforward theme: the four main types of taste sensations are represented in the first words of the theme answers. I like all the phrases, but SOURPATCHKIDS is weaker than the other three because the word "sour" is used here to mean the taste sensation. In all the others, it's metaphorical.
The revealer wasn't really needed: I saw what was happening well before I got to the last answer. As revealers go, however, TASTEMAKERS is fine. I've heard the term before, so it's in common enough parlance to be of interest.
I had a little difficulty getting out of the NW and the middle N. UPTOSPEED wanted to be UPTOSnuff in my head, but I didn't put it in because it seemed a little... well, not up to snuff, if you catch my drift. Similarly, ONEBYONE wanted to be ONEatatime, but that didn't fit. I also wasn't sure about the ending of RUSHWEEK. No frats or sororities in my undergraduate existence.
So I was a little surprised that I hadn't posted a longer time. It helped that both the SW and NE corners I was able to fill in with only the down answers. Some nice answers elsewhere included NEATNIK and KODAKS (although I don't love the plural here; at least it's better than OMEGAS, or SPATES, for that matter).
I knew Nicolas ROEG's name, but didn't know he directed The Witches. I recall Walkabout as being a very good movie.
1A: ____ above (better than) (ACUT) gets an F, I'm afraid. It's a partial to start a puzzle. 1D: Jessica of "Dark Angel" (ALBA) was my first solid entry.
Not a bad Monday.
