[Devil May Cry] What are the odds that I can complete this game?

[Teggy]

I picked up DMC (the first) this weekend and played up to the first boss -

Spoiler for Hiden:

the spider

.

I think I have a pretty good handle on the moves you are given at the start of the game - I was using "high time" fairly deftly to knock guys in the air and juggling them with my guns until they blew apart. I was dodging pretty effectively.

However, when I hit the first boss I was dispatched in almost no time.  I tried about 4 times and was able to keep adding on a little damage, but each time was killed in under a minute.

I know this game has a rep for having a steep learning curve. Am I setting myself up here for epic frustration?  Should I sit down and see if I can work this out, or should I just pack up the whole 5th anniversary set on eBay and move to something else in my expansive backlog?

Vegas has the odds at 20 to 1.

I say pack it up and play God of War instead.

I've played (and beaten) God of War on normal. There's God of War 2, but I won't pick that up until I've knocked a bunch off the backlog.
