The show is quite frankly a mess, writing wise.
The first episode, written by the creator of the comic book, did well and struck a good balance between humor, action and drama.
They haven't been doing so well since then, and admittedly the shameless sweeps bait is not faring much better.
It's like the show doesn't know what it wants to be and who it wants to be for, as it usually the case for network shows lately, as they desperately want to reach younger audiences than the usual senior homes and leave it to beaver families watching their shows, but remain completely unable to accept that they will have to sacrifice the baby boomers if they want to get anyone born after 1980 interested.
It doesn't help that ABC seems to believe (thank you Grey's Anatomy?) that female led shows can only be interesting to female viewers if there are love interests, love triangles, boy trouble and all the usual BS that comes with "shows for women" from the early 2000s and before.
So was this a good episode? No. Why? Because it wasn't sexy enough? or because the guest lesbian wasn't hot enough? or because "homosexuality ruins everything" (LOL)?
Nope. Because the writing was bad and the character in the comics is bisexual through and through. Not just when it's about getting old pervs to watch the show during sweeps.
And by the way, Cobie Smulders is a producer on the show. IF she didn't want to do a gay scene, she wouldn't have picked a comic book whose character is bisexual. Then network happened.
