This week was way better though, as it wasn't saddled with an alien plot at the same time; not dissing it though, the whole "Invasion!" thing was a great adaptation of how comic books do crossover arcs by focusing on each book / show / team's own part in the overall story while incorporating all sorts of goodies from the other entries.
I think that's pretty normal for TV crossovers too. Like in last season's Bones/Sleepy Hollow crossover, the Bones half was mostly Bones stuff with some SH guest stars, and the SH half was mostly SH stuff with some Bones guest stars.
