Totally understandable. While most of us thought a deluge of Thor books might be a good thing I think with hindsight its just muddying the waters. As I see it there are several problems.
1. Theres just too many to keep up with. There must be about a dozen different titles between now and the end of the year. Its just an overload. They are going from one comic a month to about 5 or 6 a month. Its too much to ask, especially in the current $3.99 climate (which is really a $4.99 climate for us in the UK).
2. The vast majority are all out of continuity.
3. The deluge of titles is really taking away the spotlight from Fractions run.
In my opinion they should have just had 1 Thor title, 1 Ultimate Thor title and maybe 1 out of continuity mini-series (at a time).
Son of Asgard was brilliant, Stormbreaker was great, Loki was excellent.
But its just like Marvel have said, "Okay theres a Thor movie out soon, lets throw as much poop at the wall as we can and see what sticks!"
Thats not to say there might indeed be some good stories coming out, but I'd rather have two great mini-series than half a dozen 'meh' ones.
