Actually talent is not subjective. Talent isn't up for opinion. There are varying degrees of talent. But, either a person is talented of they aren't. About 90% of all auditioning actors SHOULDN'T. They should be looking for real day jobs because they will never succeed in their chosen profession. That might sound mean. But, if you sit in on enough auditions, you'll find it to be completely true.
If you watch reels and think about anything other then talent, then don't watch reels. The only thing that matters in an actors reel is if they can act. Chances are if an actor has a reel the footage isn't going to look that great. Because if they need a reel they're probably just starting out. Any established actor will just point to reviews and their agent.
On a scale of 1 - 10, with Meryl Streep being a 10 and Pamela Anderson being between a 3 - 4. Jane is a 7. She's pretty close to that group where she instinctively knows what needs to be done and does it. That's nowhere near average or the norm. If you need to see it, look at her expressions, her timing when the red-head speaks. Look at her face when she says the lines. Is she natural and being truthful? Is she acting?
You're judging material. You don't have to like what they're doing. But are they doing it well? Do you see gaping flaws? Are these the director or the actor's fault? That's what you have to ask yourself. That's what you have to look for. Talent isn't subjective if you know what you're doing and what to look for.
Being able to spot talent is a talent in and of itself.
To call Jane typical is just wrong. She's a specific type. But, she's a very good specific type. That's a fact, not opinion.
