I've only seen the pilot so far, but the main characters have great comedic timing and great chemistry with each other - that's rare to get in a pilot.
Sure, the show is a little silly, but it's a buddy comedy - it's supposed to be silly! And the two main characters pull off the ridiculous moments really well (and make them entertaining), which is something that a lot of new shows fail at.
Franklin, in my opinion, is the funnier of the two, but they're really best together. You completely get that they've been friends for a long time and are very close. The moment in the pilot when they realize their new job has them in separate offices is hilarious - they both seem confused at being separated and have the wall between the offices taken down to make one big one. Just their faced and timing on the lines alone make it very funny!
I hope this show stays good and gets better. I worry about really fun pilots that I like because that tends to signal that the show won't stay good. Here's hoping that doesn't happen with this one!
I recommend that you give this a shot. If you like things like "Psych" that have two buddy main characters, you might like this, too.
