Matt Roush: Lots of confusion on this topic. (Thanks, NBC, for trumpeting such misleading promos.) Tonight's episode is absolutely not the series finale — Heroes is going to run for years, trust me — and everyone's hoping it won't be the season finale, either. The situation is that this episode is the "finale" of the current virus-threat arc, or at least that's how it's being billed, and this is the last completed episode before the strike shut down production. When the strike is over — let's all hope it's soon — filming will resume for the back half of the season. There may be more of a gap between episodes than the show or the network would have preferred, but unless the strike drags on indefinitely, there will be more Heroes before the season is over. How many or when, no one can say just yet. Same goes for all of the other established series worried fans keep asking about. As for my thoughts on Season 2 to date: I thought it started off as bad or worse than the beginning of Season 1, embracing clutter over clarity. But just like in Season 1, it eventually kicked into high gear, and from around the time when Matt's "nightmare man" father was introduced, along with Kristen Bell's feisty Elle, the show has been a lot more entertaining. I'll miss it.
