A thick TP that gathers ten issues: New Mutants #98, Deadpool #1 - #4 (The Circle Chase), Deadpool #1 - #4 (Sins of the Past), Deadpool #1.

Everything except Deadpool #1 is in a 80s/90s drawing style. The New Mutants issue is kind-of unneeded, but there you supposedly see a first meeting between Deadpool and Cable.
The story in the first Deadpool #1 - #4 regards someone's last will where he supposedly gives a very strong weapon to whoever inherits him, and it's a mad dash to find the will and to discover where that powerful weapon is held.
It's a nice fight between several people and the drawing is nice excluding several parts. I think it's a joint effort and that the colorist, inker, penciller and letterer all deserve the credit - they created a nice look together.
The beginning of this arc and the story itself aren't very interesting, but the weapon that appears in the end is interesting and there are some nice characters in this - mainly Weasel.

The second Deadpool #1 - #4 arc is about a man who suffers from a sickness and he needs to capture Deadpool so he can be cured. You get in here (also in the previous arc) a nice insight into Deadpool's personality and why he is wearing a mask and you see a more vulnerable side of him and how he became Deadpool.
You basically see why he separates himself from society and why he goes on these suicidal missions (that despite his abilities are still very dangerous) and why he treats the world with irreverence and why he jokes all the time.
There is a heavy use of ink and some places look like the inker and colorist were changed - the colors are more sickly/muted looking and there is less ink, and it's mainly in the beginning of the second part - which suits it and is very nice, but when it appears out of nowhere and returns to normal pretty quickly it gets annoying.
There are several places like that.
There are some panels that are too crowded and one panel where the Juggernaut and Deadpool fight and I still don't know what the hell was happening in that panel.
There are some details that disappear and reappear like the cut in Syrin's forehead - that's the fault of the inker (maybe also the penciller?), a wound that is on part of the body and then all of it and back again to being only on part of the body - which is the colorist's fault (maybe also the penciller?) but it didn't really bother me.
The drawing is very good sometimes and interesting and could have been better with a lesser use of ink - the inker is good but he overdoes it sometimes.
There is a hilarious panel that comes out of nowhere where we see that Syrin's costume is torn and we see a part of her bra, and that threw me off and made me laugh because it appeared out of nowhere - a gratuitous booby shot.

The last part is done mostly in the computer - you can see it in the coloring, drawing and lettering, but it didn't bother me - the drawing was good and I got sucked into the comic despite my repulsion of computer-heavy comics.
Here Deadpool takes a job to kill a mutant and things don't go exactly as planned, and the end of the job holds a surprise for Deadpool. A pleasant part - it shows some interesting characters and the idea of a hired killers' job placement agency is funny and nice.

If you don't know who the hell is Deadpool: Deadpool is a hired mercenary with regenerative abilities, an ability to teleport - those two don't always work mind you, and he keeps cracking jokes.

This TP has a #1 on it and I doubted there will be a #2 because: what will they put in it? But a second TP came out...
I can't recommend reading this TP but the two long parts are nice and they show that Deadpool has potential, and the last part (Deadpool #1) shows that he can be funny.
Also there's the benefit of him being in the Marvel universe. Also he has a big emotional baggage which you can see in the two long arcs but I doubt that that side of Deadpool will be shown again, but this TP made me interested in the character.
The only question is what to buy next: Deadpool #-1, Deadpool #1 or Cable & Deadpool #1 or go for the minis instead.

At the end of the TP there are some drawings in different stages  - they are from the last part (Deadpool #1) - with text and parts of the script that show us how that issue was made, and it's a nice look into the process and a nice extra.
Also - keep in mind that the drawing in most of this TP is sometimes problematic - sometimes it's hard to understand what's going on in the panels.
