daisy_knotwise and I watched the last two episodes of Heroes last night. We'd intended to watch one, but decided that we didn't want to wait to see what happened and since everything was on the DVR, we had the option. :) (We got started watching this season late, because we were out of town for the premiere. samwinolj was good enough to record the two-hour episode for us, but it took a while to get the DVD from him, so Heroes languished until we did.)
I'll avoid spoilers. What I will say is this: if you'd given up on the show, this was the season that you've been waiting for. It was probably the strongest season/volume to date. The character work was strong, nothing happened that caused me to roll my eyes and go "Oh, God, what now?", and I actually wanted to tune in from week to week -- if at a somewhat late date.
I'm sure it will be out on DVD fairly soon. Rent it. Buy it. Watch it. If you ever liked the show, you'll like this.
I hope we get another season (despite the lousy ratings), because the show actually deserves one now.
