This is exactly what lovers of the original Drew-hosted Whose Line want: More Whose Line.
There's not a whole lot to say other than address the main negative comment from viewers:
"No Drew Carrey, and not-so-funny-host now." Well... boo hoo. I did notice that Aisha Tyler hasn't made me laugh as much as Drew might have, but that was because she isn't telling enough Points-Don't-Matter jokes, and jokes in general. She seems to be more or less the announcer no one truly looks forward to. But she's okay, honestly. I've never known her until Whose Line, and she's a fun person who reacts to the guys in ways that make you wanna laugh too. Drew Carrey was pretty much there for the same thing, and fat jokes. And he's no longer fat. (in short, he wasn't a particularly funny guy either, at least alone) I like Aisha. She might need to tell more jokes though, and they don't have to be original.
More positive criticism: I enjoy how they leave one seat open for a guest player to participate in. Having one seat open--while Colin, Ryan, and Wayne are planted on the show--allows for many different folks from various areas in the world of comedy to sit in. Back in the day, Steven Colbert was on the show, and it was awesome. Perhaps he can reunite and be in the second chair again.
Another note which is up for debate is about how Whose Line is now on the CW.22, and a lot of guest stars are stars from CW shows. Whose Line is becoming promotional for the Dramas comedy lovers wouldn't normally care about. I only watch CW for Whose Line. But if someone might be interested in something different while watching it, they also might love the show that Whose Line promoted, so... it's debatable.
Lastly, Whose Line is genuinely funny, not 'again' but 'still.' Wayne, Colin, and Ryan are all themselves still, and the show so far has made me laugh as much as the original, at a similar show intake of course. I don't expect EVERYTHING to be the same, and to those that think the show isn't the same any more...
Ryan Stiles, Colin Mochrie, Wayne Brady. Laura Hall, Linda Taylor. "Whose Line Is It Anyway?" "The points don't matter," along with a bundle of the classic games that were played...
So shut up.
I'm excited to sit down every Tuesday for this show. Potential is no longer the story; this show is freaking funny as hell... and that's all that should matter.
