Why Django serialize returns string

I have problem with returning something browsable form serializers.serialize.

My model:

class BowlingGame(models.Model):
    Frame = models.PositiveSmallIntegerField()
    FrameRow = models.PositiveSmallIntegerField()
    Result = models.PositiveSmallIntegerField(blank=True, null=True)
    StrikeSpare = models.PositiveSmallIntegerField(blank=True, null=True)
    StrikeSpareInfo = models.CharField(max_length=1, blank=True, null=True)
    Time = models.DateTimeField(blank=True, null=True)
    GameId = models.PositiveIntegerField()
    StateOfGame = models.PositiveSmallIntegerField(default=1)

    class Meta:
        ordering = ('GameId',)

    def __str__(self):
        return str(self.GameId)

And what I do next:

>>> from django.core import serializers
>>> from django.db.models import Max
>>> from game.models import BowlingGame
>>> a = BowlingGame.objects.all().aggregate(Max('GameId'))['GameId__max']
>>> game_frame = BowlingGame.objects.filter(GameId=a)
>>> me = serializers.serialize('json', game_frame, fields=('Frame', 'FrameRow'))
>>> me
'[{"model": "game.bowlinggame", "pk": 2356, "fields": {"Frame": 1, "FrameRow": 1}}, {"model": "game.bowlinggame", "pk": 2357,......}}]'

This seems to be string as 

>>> me[0]
'['

and I'm looking for the first element of the queryset.

I tried few more things:

>>> me = serializers.serialize('json', [game_frame, ], fields=('Frame', 'FrameRow'))

AttributeError: 'QuerySet' object has no attribute '_meta'

My question: is it normal to return string? How I can browse the object. In fact I'm using it with AJAX but its the same. json.game_frame[0] returns '['. I need to be able to get the elements separately as normal dict or list. What is going on?

I just find a solution. In my javascript file var content = JSON.parse(json.game_frame). It creates nice browseble objects.
